How to read the notation

Sequences run from the N-terminus to the C-terminus in one-letter code. An uppercase letter is one of the twenty standard L-amino acids; a lowercase letter is the D-form of that residue; a [bracketed] code is a non-standard residue such as [Aib] (2-aminoisobutyric acid) or [Nle] (norleucine); a group in (parentheses) is a side-chain modification on the residue before it, such as the fatty-acid chain on semaglutide's lysine. Ac- marks an acetylated N-terminus and -NH2 an amidated C-terminus. Disulfide bridges, cyclisation and bound metals are listed on each monograph rather than written into the string. The terms are defined in the glossary entry on sequence notation.

Molecular weights are average masses of the free base; salt forms (acetate, trifluoroacetate) weigh more. Shortest chain: Noopept. Longest: Dulaglutide. Records marked medium or low confidence rest on a single or a secondary source and are flagged for re-checking.

Why a sequence page on an evidence site

Two products can share a name and not a molecule. TB-500 is not the 43-residue thymosin beta-4 that ran the eye-drop trials; CJC-1295 with and without its albumin-binding linker are different drugs with half-lives days apart; "insulin" on a label is one of a dozen analogues. A stated sequence is the only unambiguous way to say which molecule a claim, a trial or a vial refers to, and it is the first thing a certificate of analysis should be checked against. The mass-spectrometry identity check on a certificate is meaningless without the expected mass, which is why the formula and molecular weight sit beside each sequence here.
