[Proteolysis of milk proteins in young children].

Distinct pancreatic activity was observed in duodenal chyme of newly born children. Rapid evacuation of protein from stomach was noted in artificial feeding. The tryptic activity was increased in duodenal contents after the introduction of artificial feeding. Amino acids were mainly liberated in the course of cavitary digestion of proteins. Some of the amino acids (cysteine, phenylalanine) were absorbed in a bound form.
