Unique ID
D010455
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D010455
Annotation
general or unspecified; prefer specifics; fewer than 13 amino acids = oligopeptides; "primary structure" = PROTEIN STRUCTURE, PRIMARY see AMINO ACID SEQUENCE; peptide structure other than primary: coordinate with PROTEIN CONFORMATION or its specifics
Scope Note
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 considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.
