What This Is

150 peptide molecular icons built from real amino acid sequences. Each bubble represents one amino acid residue. Bubble size maps to residue mass. Bubble color maps to one of five biochemical classes: hydrophobic, polar, positive charge, negative charge, and special.

• 102 icons from verified amino acid sequences
• 27 simplified icons (non-standard residues mapped to closest standard match)
• 21 compound icons (non-peptide molecules like MK-677, NAD+, L-Carnitine)

Install

npm install @peptideschedule/icons

Usage

HTML

<img src="node_modules/@peptideschedule/icons/icons/dark/bpc-157.svg" width="48" alt="BPC-157 molecular icon" />

React

import bpc157 from '@peptideschedule/icons/icons/dark/bpc-157.svg';

function PeptideIcon() {
  return <img src={bpc157} width={48} alt="BPC-157 molecular icon" />;
}

What the Icons Encode

| Visual Property | Maps To | |----------------|---------| | Each bubble | One amino acid residue | | Bubble size | Relative residue mass (Trp = largest, Gly = smallest) | | Bubble color | Biochemical class (hydrophobic, polar, positive, negative, special) | | Bubble count | Total residue count in the peptide chain | | Ring layout | Cyclic peptide structure |

What the Icons Don't Show

• Stereochemistry (D/L amino acids look the same)
• Post-translational modifications, PEGylation, fatty acid chains
• 3D folding or receptor binding
• Biological activity or potency claims
