A short chain of amino acids (typically 2-50 amino acids) linked by peptide bonds. Shorter than proteins but with diverse biological activities.
"Peptide" is filed under Basics in the PeptideAtlas glossary, alongside 12 other terms in that group.
The term applies directly to 95 compound profiles here: BPC-157 (evidence C), Tirzepatide (evidence A), Selank (evidence D), Semax (evidence D), DSIP (evidence D), SS-31 (evidence A), KPV (evidence D), FOXO4-DRI (evidence D), and others. Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
99 other glossary entries refer to this term in their own definition, which is usually the fastest way to see how it is used in practice.
The building blocks of peptides and proteins. There are 20 standard amino acids that combine in various sequences to form peptides.
The specific order of amino acids in a peptide chain, typically written using three-letter or one-letter amino acid codes. Determines the peptide's structure and function.
A modified version of a naturally occurring peptide, engineered to improve stability, bioavailability, potency, or half-life. Semaglutide is an analogue of GLP-1.
The chemical bond formed between two amino acids when the carboxyl group of one reacts with the amino group of another, releasing water.
