Medical Condition:
Polypeptides

Any member of a class of compounds of low molecular weight which yield two or more amino acids on hydrolysis. Formed by loss of water from the NH2 and COOH groups of adjacent amino acids, they are known as di-, tri-, tetra- (etc.) peptides, depending on the number of amino acids in the molecule. Peptides form the constituent parts of proteins. (Dorland, 27th ed)
