peptide

 [pep´tīd]
any member of a class of compounds of low molecular weight that yield two or more amino acids on hydrolysis. They are the constituent parts of proteins and are formed by loss of water from the NH2 and COOH groups of adjacent amino acids. Peptides are known as dipeptides, tripeptides, tetrapeptides, and so on depending on the number of amino acids in the molecule. See also polypeptide.
vasoactive intestinal peptide vasoactive intestinal polypeptide.

pep·tide

(pep'tīd),
A compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another, with the elimination of a molecule of water, thus forming a peptide bond, -CO-NH-; that is, a substituted amide.
See also: polypeptide. Compare: eupeptide bond, isopeptide bond.

peptide

(pĕp′tīd′)
n.
Any of various natural or synthetic compounds containing two or more amino acids joined by peptide bonds that link the carboxyl group of one amino acid to the amino group of another.

pep·tid′ic (-tĭd′ĭk) adj.
pep·tid′i·cal·ly adv.

peptide

A biomolecule consisting of two or more amino acids joined by a peptide bond, which combine to make proteins.

pep·tide

(pep'tīd)
A compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another, with the elimination of a molecule of water, thus forming a peptide bond, -CO-NH-; i.e., a substituted amide.
Compare: bioregulator

peptide

A chain of two or more AMINO ACIDS linked by peptide bonds between the amino and carboxyl groups of adjacent acids. Large peptides, containing many amino acids, are called polypeptides. Chains of linked polypeptides, are called PROTEINS. Peptides occur widely in the body. Many HORMONES are peptides.

peptide

any of a group of compounds consisting of two or more amino acids linked by chemical bonding. See PEPTIDE BOND, DIPEPTIDE.

pep·tide

(pep'tīd)
Compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another, with the elimination of a molecule of water, thus forming a peptide bond.
