生化/生理作用

Due to the action of enzymes such as trypsin, amylase, and lipase, trypsin can hydrolyze proteins, starch, and fats. Pancreatic enzymes can convert no less than 25 times their weight of potato starch into soluble carbohydrates in water at 40 ° C within 5 minutes. They can digest no less than 25 times their own weight of casein in 60 minutes at 40 ° C and pH 7.5, and release no less than 2 micro equivalents of acid per milligram of pancreatic enzymes per minute from olive oil at 37 ° C and pH 9.0. Pancreatic enzymes are produced by exocrine cells of pig pancreas and contain enzyme components such as trypsin, amylase and lipase, ribonuclease and protease. This combination of enzymes enables it to hydrolyze proteins, starch, and fats. In 40 ° C water, trypsin converts no less than 25 times its weight of potato starch into soluble carbohydrates within 5 minutes. At pH 7.5 and 40 ° C, trypsin digests no less than 25 times its weight of casein within 60 minutes. At pH 9.0 and 37 ° C, every milligram of trypsin releases no less than microequivalence of acid per minute from olive oil
