Thesaurus

Noun

polypeptide - a peptide containing 10 to more than 100 amino acidsprotein - any of a large group of nitrogenous organic compounds that are essential constituents of living cells; consist of polymers of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs and milk and legumes; "a diet high in protein"peptide - amide combining the amino group of one amino acid with the carboxyl group of another; usually obtained by partial hydrolysis of protein

Translations

polipeptide

polypeptide

polypeptide:

see peptidepeptide,
organic compound composed of amino acids linked together chemically by peptide bonds. The peptide bond always involves a single covalent link between the α-carboxyl (oxygen-bearing carbon) of one amino acid and the amino nitrogen of a second amino acid.

Polypeptide

an organic compound containing six to 80–90 amino acid residues; the upper limit corresponds to a molecular weight of about 10,000. Such polypeptides, unlike proteins, can pass through semipermeable membranes.

The simple polypeptides are crystalline substances that are readily soluble in water and have chemical properties similar to those of amino acids. The complex polypeptides are amorphous and react with water to yield colloidal solutions. Polypeptides are formed in the organism during enzymatic proteolysis (autolysis of tissue, digestion, and so on) and during biosynthesis from amino acids. Many natural polypeptides exhibit the biological activity of hormones, antibiotics, and toxins. Synthetic polypeptides serve as models in studying the structure and biological activity of proteins.

polypeptide

[¦päl·i′pep‚tīd] (biochemistry) A chain of amino acids linked together by peptide bonds but with a lower molecular weight than a protein; obtained by synthesis, or by partial hydrolysis of protein.

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

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