What peptides share
Peptides contain amino-acid-derived units connected by amide bonds. Proteins are also built from amino acid chains and may contain one or more folded chains. These categories do not assign a shared function to every molecule they encompass.
What identifies a particular molecule
To compare materials, record sequence, modifications and chain termini when declared. An abbreviation or residue count is insufficient to establish equivalence. The word peptide also does not establish purity or clinical outcomes.
