Definition English:   Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES. 
Indexing Annotation English:   general; prefer specifics; fewer than 13 amino acids = oligopeptides; "primary structure" = PROTEIN STRUCTURE, PRIMARY see AMINO ACID SEQUENCE; peptide structure other than primary: coordinate IM with PROTEIN CONFORMATION or its specifics
