Bare Signals · Aminos
Twenty-one bare amino acids. Chained in the right order, they become peptides and proteins: bare signals that tell the body what to do. A walk in three parts: the letters, the build, the fold.
Getting to know the building blocks
Peptides are short chains. Proteins are long, folded ones. No single length divides them.
Think of this as the periodic table of life. Every peptide and protein in your body is spelled from these 21 letters, in different orders and lengths. Each tile is one amino acid: tap it to see its structure, its weight and what it does in the body.
Watch a gene become a peptide, one step at a time. Not every peptide here is made this way: some are cut from bigger proteins, some are designed in labs. This is how a gene would spell each one.
The source code
The working copy. Transcribed, every T becomes U.
Three letters, one amino acid
The peptide. Each link is a peptide bond.
One continuous chain. N is the amino end, where the first amino acid still has its free nitrogen group (NH₂). C is the carboxyl end, where the last one still has its free acid group (COOH). The ribosome always builds from N to C, adding each new link at the C end. Long chains fold into shapes; short ones often stay loose.

Not peptides, often paired with them
As chains grow longer, most become proteins. Stretches of it coil into helices like this one, others pleat into sheets, and the whole chain packs into a working shape.
An alpha helix turns every 3.6 amino acids.
Past 50 links, chains stop being strings and become machines. Several folded chains often work as one. Five you already know, each a different shape for a different job.
Built over 40 rounds of edits by Cece, 21 to 22 October 2026. Every version below was a new round of her notes; old versions are kept, not overwritten.
V40: the copper atom on GHK-Cu and AHK-Cu turns sapphire blue, the colour copper gives the vial, with the note why the vial is blue. It is the one colour on the page outside the Bare Signals palette, kept apart from Sleep’s brighter blue.
V39: How to read a tile starts closed, as a small box. The tile key’s signs are now orange, matching the tiles. In the moving walk the mRNA wave settles flat at both ends so DNA, mRNA and codons join cleanly, and the turn between rows is one soft curve instead of square corners. Show all now also sits right under the search box. Search understands origin words: not a peptide, lab-made, natural, fragment, modified, enzyme-made. The search box no longer zooms the page on iPhone. GHK-Cu and AHK-Cu show their copper atom bound to the chain. Five famous folds renamed Proteins you already know.
V38: in every map of where a peptide sits inside its parent protein, the known links now carry their real amino acid colours, the same as the chain beads, with the letter on hover. BPC-157’s 15 known links between the question marks are coloured the same way.
V37: the page title is now From gene to peptide, with Aminos as the label above it; Part two becomes Build a peptide. The moving walk gains RNA polymerase, the enzyme that unzips DNA and writes the mRNA, sitting where the strands part, so the mRNA comes straight out of it. Motion runs at full frame rate. The amino acid bead now shows its name underneath. Part one gains a short introduction and a How to read a tile key (full name, three-letter code, one-letter code, weight, codon pips, stripe), and every amino acid card now says how to pronounce it. In Part three, Amino acid on the ladder jumps back to the 21 tiles, and Complex opens Five famous folds: collagen, keratin, hemoglobin, antibodies and myosin, each drawn with its size, job and one surprise.
V36: on laptops, Part two becomes two columns: the build on the left, the peptide picker beside it on the right third, staying in view while you scroll. Popular gains Show all, which opens every entry with sorting: popular, shortest, longest, A to Z, or grouped by origin (made by the body, cut from a protein, made by enzymes, lab-modified, lab-designed, reference, not a peptide). BPC-157 now sits between question-mark ghosts, since the rest of its parent protein is unknown. Every chain, even two or three links, now rides the S-curve. The fold at the top turns with the chain instead of against it. Bigger type for Aminos, the part labels and The 21 amino acids.
V35: the top is now a moving lesson: one string comes in from the left, touches the DNA ladder with its coloured A, T, C, G teeth, unzips into orange mRNA, is read three letters at a time, drops amino acids, links them into a chain and coils into a helix, in six captioned steps. Every entry’s origin line rewritten as a short story: who found it, how it got its name, the surprise. Khavinson bioregulators explained by tissue. Chains of ten or fewer now all use the large Vilon bead size; longer ones shrink gradually.
V34: the page now reads as a walk in three parts, with Part one · The letters added above the 21 tiles and Part three renamed The fold. New opening line: bare amino acids become bare signals. Thymosin Beta-4 opens as the First example, its name underlined with its full four-colour stripe instead of one green line. The non-peptide row reads often paired with them. Eight new entries: Retatrutide, Cagrilintide, Somatropin (HGH, 191), Gonadorelin, Larazotide, Carnosine, plus Creatine and Methylene blue as non-peptides with made-of panels. The two CJC-1295 forms now explain their difference.
V33: helix beads now cycle through the full palette instead of the last chain’s colours. Chain beads scale with length: chains of six or fewer keep the Vilon size, then beads shrink gradually down to the old size near 36 links. Every chain longer than six now rides a gentle wave, so mid-length peptides like oxytocin and BPC-157 look like they are starting to fold. Single-row chains sit centred. Two more non-peptides: MK-677 and SLU-PP-332. The 21 amino acids heading gets room above it, with the tap hint on its own line on phones.
V32: picking a non-peptide now scrolls up to its panel instead of dropping toward Then it folds. For non-peptides, step 05 loses its number and reads What it is, since nothing is built. The Building line is centred: a small label on top, the name as large as the step numbers, try another underneath. Non-peptides left the Popular peptides and got their own row: Not peptides, often paired with them. Glossary words orange, meanings back in the page’s blue. The made-of type line is centred plain capitals, no box, so it no longer looks like a button.
V31: a magnifier in the pick and search box. Glossary rewritten to two or three sentences per term; amino acid, peptide and protein now in orange, word and meaning alike. Three new terms: nucleotide, small molecule, coenzyme. The four non-peptides now show what they are made of instead of an empty panel: NAD+ as its six parts, 5-Amino-1MQ and Bromantane as rings, cage and atoms, Cerebrolysin as a soup of loose amino acids and short chains, each with formula and weight.
V30: arrows removed; each step now carries a large orange number instead. Fold to one line moved under the codons, bottom right. The N and C ends explained in a short paragraph. Chains of six or fewer sit centred with big beads, so tiny peptides look as small and whole as they are. Added Insulin, shown as proinsulin (86) with its history, FOXO4-DRI, and NAD+, 5-Amino-1MQ, Cerebrolysin and Bromantane as not-a-peptide entries that explain why there is no chain; NAD+, Humanin, Glutathione, Cerebrolysin, FOXO4-DRI and Bromantane joined the popular list. V29 unchanged.
V29: glide a finger or mouse along the chain and each bead names itself as you pass; it lingers where you stop, then fades. Thymosin Beta-4 renamed, underlined in its colour in the Building line. Arrows are now solid orange triangles; tighter gap before Built. Fold control in its own orange box. More popular peptides (44 on phones, 48 on laptops). Every entry in the list shows its origin and flags proteins; the banner says a protein when it is one. Added five reference peptides for comparison: GLP-1, Glucagon, Exenatide, Amylin and Ubiquitin (76, a true protein). The close now climbs a ladder, amino acid to dipeptide to protein to complex, with your current build lit; tap a rung to load an example. Helix gains a yellow ribbon. V28 unchanged.
V28: the walk now builds first and reveals after: DNA, mRNA, codons and chain come first, then step 05 shows what you built, with the peptide’s banner, colour key, origin and numbers together. A small line at the top says which peptide is building, with a jump to try another. Popular now shows 36 peptides on every screen. The helix beads take the colours of the chain you just built. V27 unchanged.
V27: full DNA, mRNA and codons show by default, with one orange Fold to one line control above them that folds all three into swipeable lines, each giving a small sideways nudge to show it swipes; Expand code brings them back. Fixed lines not returning to normal after folding. Arrows larger and orange; step text moved closer together; T and U letters bold orange. Hover or tap any bead in the chain to see its name, code and position. Linked by peptide bonds moved beside Chain. V26 unchanged.
V26: fold control is now a clear button at the bottom right of each long step (Expand code, Fold back to one line), with the count on the left. The T becomes U note moved beside mRNA; the read three letters note removed. Accuracy pass from an outside review: peptide and protein no longer split at a fixed 50; chains fold only when long; amino acid sources use the standard terms (essential, conditionally essential, nonessential); colour keys marked as research associations; weight for modified peptides labelled backbone only. V25 unchanged.
V25: each peptide now says where it really comes from: made by the body, cut from a protein, lab-modified, lab-designed, or made by enzymes. Where the parent protein is known (TB-500 fragments, KPV, Sermorelin, CJC-1295, Kisspeptin-10, growth hormone fragments, Teriparatide, LL-37), a small map shows its position in the original chain, with the rest faded. On phones, long DNA, mRNA and codons fold to a single swipeable line with a count and a show-all toggle. Top copy sharpened; protein set in bold at the close. V24 unchanged.
V24: the translator becomes Part two, a walk from gene to peptide under a large centred title: 01 DNA, the source code; 02 mRNA, the working copy; 03 codons; 04 the chain; 05 what you built, joined by dashed arrows (transcribed, read three letters at a time, linked by peptide bonds). Each step lifts into view as you scroll, laid out as label and content side by side on laptop and stacked on phones. Picking a peptide scrolls back to the top so you watch it rebuild. Part three closes the page: past 50 amino acids the chain is a protein, shown as a slowly turning alpha helix, with a button that loads IGF-1 LR3. V23 unchanged.
V23: translator opens on TB-500 (Tβ4), now first among the popular chips. A one-line colour key sits under the banner naming each stripe block in order. Tile names a size up; the short code now sits right under the name, and the codon pips drop to the bottom of the tile, leaving clear space between. V22 unchanged.
V22: tiles lead with the full name in bold (Lysine, Tryptophan) instead of the letter. The one-letter code sits large and faint in the bottom corner like a watermark; the essential square and the charge, ring, sulfur, start and BCAA signs stack in the top corner; codon pips stay bottom left, so nothing overlaps. On phones the name and watermark are smaller with more breathing room. V21 unchanged.
V21: order is now banner, chain, DNA, mRNA, numbers, so the chain is the first thing you see. DNA is shown as dark source code with its T letters lit, labelled the source code; mRNA is labelled the working copy, with every U lit in the same orange so the T to U swap reads at a glance. Tap the code to type your own. The bead string replays its reveal each time it scrolls back into view after leaving the screen. V20 unchanged.
V20: fixed the bead string replaying on phones while scrolling: Safari reports a resize every time its address bar slides in or out, and the page was redrawing the string each time. It now redraws only when the screen width truly changes, and without the animation. The reveal itself is slower and calmer (about half a second longer). V19 unchanged.
V19: bead string about 20% smaller; N and C ends now large orange letters. The Now translating banner carries the peptide’s sticker stripe on its right: up to four blocks in the Canva layout (two stacked, one medium, the widest on the right), scaling with the screen. New glossary under the version log with 30 terms used on the page. V18 unchanged.
V18: the chain is now drawn as beads on one string, snaking left to right and back like an S, from the N end to the C end, with a note that in the body it folds. mRNA codons sit on one continuous tape instead of separate boxes. The DNA box grows to fit the whole sequence and breaks lines cleanly on phones instead of cutting text off. V17 unchanged.
V17: the translated peptide now has its own banner: a band in its sticker colour, a "Now translating" label, the name in large type, and its length and main category. On laptop the taller banner gives the popular list room for one more row of peptides, filled automatically. V16 unchanged.
V16: laptop translator split again: search and popular peptides on the left, the result on the right. The popular chips keep adding more peptides from the catalog (shortest first) until they reach the bottom of the residues, weight and class boxes, and a short last row is dropped instead of being stretched into wide blocks; the fill re-runs when you pick a peptide with a longer chain. Phone unchanged. V15 unchanged.
V15: tighter copy throughout (intro, peptide vs protein line, translator note, structure note, weight note). Search list now covers every peptide in the catalog with a known sequence: added CJC-1295 with DAC, IGF-1 LR3 (83, the longest), PEG-MGF, GHK (no Cu), AHK-Cu, SNAP-8, Adipotide and the bioregulators Cardiogen, Chonluten, Bronchogen, Ovagen, Pancragen, Livagen, Prostamax, Vesugen, Vesilute and Cartalax, each in its sticker colour; searching "bioregulator" finds the whole family. V14 unchanged.
V14: structure drawing now shows each amino acid’s real side chain in orange (chains, branches, rings, Proline’s ring back to the nitrogen) on the same backbone, instead of one generic drawing with only the formula line changing. Section title renamed from The 21 to The 21 amino acids. V13 unchanged.
V13: translator reordered: the result (name, DNA, codons, chain, residues, weight, class) now sits right under the intro line, then the All peptides search, then the Popular chips. Full width on laptop, and the laptop shows 24 popular chips (Ipamorelin, CJC-1295 no DAC, Sermorelin, LL-37, MT-2, PT-141 added back) so the rows fill out; phones keep 18. V12 unchanged.
V12: laptop card no longer pinned: it scrolls with the page instead of sliding over the translator. V11 unchanged.
V11: phone only. Card back to the V2 structure with everything visible at once (name, stripe, categories, fact table, structure beside roles, weight note), no tabs, all in smaller type so it opens under the tapped row without filling the screen. The 21 tiles shrink again with smaller type. Gene to protein boxes compacted: step number and title on one line, smaller descriptions, same words. Laptop unchanged. V10 unchanged.
V10: laptop card table back to the original one-fact-per-row red table. Phone card no longer slides over the page: tapping a tile opens a compact card right under that tile’s row and pushes the grid apart, so tiles and card are on screen together; tap the same tile or the × to close, tap another tile to switch. The phone card splits into three tabs (Facts, Structure, Roles) and drops the category chips and weight footnote so it fits in about a third of an iPhone screen; the tab you pick stays picked as you move between tiles. Laptop otherwise unchanged. V9 unchanged.
V9: fixes. Card spec table rebuilt as label-over-value boxes: two across on phones, four across on laptops, codons in a wide box, so no half-empty row and no doubled borders. Structure drawing enlarged; the side chain formula and note now sit as text under it instead of being squeezed into the drawing. Long tile names break with a hyphen at a syllable (Phenyl-alanine, Seleno-cysteine) instead of mid-word. Version log folded behind a tap. V8 unchanged.
V8: phone only. Tiles 5 across instead of 4, with smaller type, so the grid is 5 rows and the key gets four open spaces beside the last tile. Popular list cut from 24 to 18: Ipamorelin, CJC-1295 no DAC, Sermorelin, MT-2, PT-141 and LL-37 moved to the search list only. Thymosin Beta-4 renamed TB-500 (Tβ4) and kept next to TB-500 frag 17–23 so the difference is visible; searching Thymosin Beta-4 still finds it. Laptop layout unchanged. V7 unchanged.
V7: laptop and phone in one page; the layout switches at 900px wide. Laptop is V6 Laptop unchanged. Phone is V6 Phone, except the key now sits open in the space beside the last tile, with no boxes around it: three columns, sorted into who makes it (must eat, sometimes, body makes it), what it is (codons, charge, ring) and what it carries (sulfur, start, BCAA). V6 Laptop and V6 Phone unchanged.
V6 Phone: card slides up as a sheet, keys inside the grid, 4 across tiles, version log folded.
V6 Laptop: two-pane layout for wide screens. Left: title, gene to protein path on one row of six, the 21 tiles as 7 by 3 with no empty boxes, and the keys. Right: the open card, pinned so it stays in view; spec table in two pairs per row, structure and roles side by side. Translator below in two halves, picker left and result right. Below 900px wide it falls back to one column. V5 unchanged.
V5: popular peptides back to the compact V2 chip: colour square, name, a middle dot and the amino acid count in italics, so the 24 sit in a few rows on a phone. The full list is now a pick list that opens when you tap the search box, A to Z with letter dividers, filters as you type, and closes once you choose. Keyboard: arrows to move, Enter to pick, Esc to close. V4 unchanged.
V4: popular peptides are now 24 separate boxes, each with its main sticker colour as a band and its amino acid count written out; 24 fills 3 columns (8 rows) and 2 columns on phones (12 rows) with no empty corner. Length bars removed from the full list, replaced by the count. Main colours read from the Canva stickers (widest block) and Stripe v3. List trimmed to compounds in the catalog; added Thymogen, Crystagen, Testagen, Thymulin, ARA-290, HGH frag 176–191, GHRP-2. V3 unchanged.
V3: translator rebuilt. Popular grid of 20 peptides from the priority list, then the full list with search and a sort toggle, shortest first by default (Vilon, 2 amino acids, up to Tesamorelin and Thymosin Beta-4 at 44 and 43). Length bars show each one against the longest. Chains over 20 residues switch to smaller cells and wrap onto as many rows as needed. Modified residues (D forms, Aib, Nle, capped ends, rings, lipid chains) are flagged under the name; weights for those are the plain chain. Stripe v3 colours where a compound has one. V2 unchanged.
V2 tweak: every tile now holds the name in a fixed two-line slot, so pips and signs sit on the same line in every box. Pale colours (Skin, Cellular energy, Cognition) lost their green edge inside stripes; the edge stays only on small swatches where pale pink would vanish on cream.
V2: coloured rules. Gene to protein boxes in Tissue repair green, spec table in Inflammatory red, tile grid in Immunity purple. Tiles now show weight next to the three-letter code, the full name in italics, codon count as pips, and signs for charge, ring, sulfur, start signal and branched-chain. Translator buttons carry each compound's main colour from Stripe v3; Pinealon has no Stripe v3 entry yet, so it stays plain. V1 unchanged.
V1: first version. 20 standard amino acids plus selenocysteine. Category colours and names taken from Bare Signals Stripe v3; chemistry class shown as dashed chips, kept outside the colour palette. Detox and clearance roles filed under Organ function until a colour is approved.
