Abstract
An extract from the posterior lobes of pig pituitaries contains a glycopeptide with a molecular mass of 3200 (± 5%). The glycopeptide is present in amounts of the same order as the hormones oxytocin and vasopressin.The peptide portion is composed of seventeen amino acid residues: aspartic acid or asparagine (3), threonine (1), serine (3), proline (1), glycine (2), alanine (3), leucine (3) and arginine (1). The carbohydrate portion, about 55% by weight, is composed of fucose (1), galactose (1), mannose (3) and glucosamine (4). The glycopeptide exhibits none of the known physiological activities of hypophysis except for a slight lipolytic activity.This publication has 25 references indexed in Scilit:
