DISTRIBUTION OF THREE MAJOR DIGESTIVE ENZYMES OF DIGESTIVE TISSUE OF TRIONYX SINENSIS

In this paper, the optimum pH, optimum substrates concentration of amylase, protease, lipase of the stomaches, pancreas and intestines of Trionyx sinensis and active effect of Nacl on the amylase were assayed, and distributions of three enzymes in the digestive tissue were determined in the optimm condition. The results showed that:activity intensity of amylase was arranged in following sequence the pancreasduodenumstomachileum and colonrectum; activities of protease was the stomachpancreasduodenumileum and colonrectum; activities of lipase was the pancreasduodenumileum and colonrectumstomach.
