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.
γ-谷氨酰循环的关键酶γ-谷氨酰转肽酶（GTP）的活性，在新生、哺乳期和成年动物（大鼠、小鼠、豚鼠和兔子）的肠道中进行了研究。在所有这四个物种中，新生动物体内GTP的活性高于成年动物。该活性在大鼠中最高，在豚鼠中几乎可以忽略不计。
