polypeptide

 [pol″e-pep´tīd]
a peptide containing two or more amino acids linked by a peptide bond; called dipeptide, tripeptide, etc., depending on the number of amino acids present.
vasoactive intestinal polypeptide see vasoactive intestinal polypeptide.

pol·y·pep·tide

(pol'ē-pep'tīd),
A peptide formed by the union of an indefinite (usually large) number of amino acids by peptide links (-NH-CO-).

polypeptide

/poly·pep·tide/ (-pep´tīd) a peptide containing more than two amino acids linked by peptide bonds.
vasoactive intestinal polypeptide  a hormone that has vasoactive properties, stimulates intestinal secretion of water and electrolytes, inhibits gastric secretion, promotes glycogenolysis, causes hyperglycemia, and stimulates production of pancreatic juice.

polypeptide

(pŏl′ē-pĕp′tīd′)
n.
A peptide, especially one composed of 10 or more amino acids.

polypeptide

[pol′ēpep′tīd]
a long chain of amino acids joined by peptide bonds. Very long polypeptides are usually called proteins. Polypeptides may be formed by partial hydrolysis of proteins or synthesized from free amino acids.

polypeptide

A chain of amino acids joined by covalent peptide bonds. Polypeptides are longer than an oligopeptides and may constitute an entire protein.

pol·y·pep·tide

(pol'ē-pep'tīd)
A peptide formed by the union of an indefinite (usually large) number of amino acids by peptide links (-NH-CO-).
Compare: bioregulator

polypeptide

A molecule consisting of a chain of AMINO ACIDS linked together by peptide bonds. A POLYMER of amino acids that may form part of a protein molecule. Polypeptides link together to form proteins.

polypeptide

a compound containing two or more amino acids linked by a peptide bond; called dipeptide, tripeptide, etc., depending on the number of amino acids present.
