title: Biologically active polypeptides in milk.
abstract: Many biologically active polypeptides have been described in the milk of several species. Various functions for these polypeptides in addition to nutrition have been proposed in the maternal body and in the breast-fed infant. These polypeptides are derived from several sources and multiple factors control their secretion into milk as well as their fate in the mother and infant. An increasing body of evidence supports the concept that they may function physiologically.
