title: The activity of gamma-glutamyl transpeptidase in the small intestine of some species of animals at different stages of growth.
abstract: The activity of gamma-glutamyl transpeptidase (GTP), the key enzyme of gamma-glutamyl cycle, was studied in the intestine of new born, suckling and adult animals (rats, mice, guinea pigs and rabbits). In all the four species, the activity of GTP was greater in new borns than in adults. The activity was highest in rats and almost negligible in guinea pigs.
