胰凝乳蛋白酶原A

胰凝乳蛋白酶原A是胰凝乳蛋白酶的无活性酶原前体。它在胰腺中合成并分泌到小肠，在小肠中经胰蛋白酶激活。牛胰腺来源的该酶原常用于酶激活和蛋白质折叠的研究。

Chymotrypsinogen A is the inactive zymogen precursor of chymotrypsin. It is synthesized in the pancreas and secreted into the small intestine, where it is activated by trypsin. The bovine pancreatic zymogen is commonly used in research on enzyme activation and protein folding.
