How to read this index

1 min readUpdated 23 Jun 2026

Every peptide in this index follows the same layout. This short guide explains each part so you can scan an entry quickly.

The sequence fingerprint

When an entry has a sequence, the coloured strip near the top is its fingerprint. Each cell is one residue, coloured by physico-chemical class:

  • Nonpolar — hydrophobic side chains
  • Polar — uncharged, hydrophilic side chains
  • Acidic — negatively charged at neutral pH
  • Basic — positively charged at neutral pH

The strip is followed by the one-letter sequence (same colours) and a composition bar. If an entry has no defined sequence — a mixture or conjugate — the fingerprint is omitted entirely.

The property table

The sidebar lists structured fields: molecular formula and weight, CAS number, PubChem CID (linked, when present), half-life, and synonyms. Only the fields that exist for a given entry are shown, so the table never has empty rows.

Statuses

Entries can be marked draft, example, or published.

  • draft — hidden everywhere; useful while an entry is being written.
  • example — visible but flagged as illustrative seed data, for entries that are placeholders.
  • published — a normal, live entry. This is also the default if no status is set.

Search

The search box matches an entry's name, aliases, tags, category, summary and — for peptides — its one-letter residue string. So searching GHK finds the copper tripeptide by its sequence, even though "GHK" never appears in the prose.
