Abstract

Human milk fat globules require colipase to be hydrolyzed by pancreatic lipase in the presence of bile salts. This is contrary to a recent report in this Journal (J. Clin. Invest. 67: 1748-1752.) according to which inhibition of lipase by bile salt could be overcome by the addition of colipase or phospholipase A2. This latter finding is shown to be due to contamination of commercially available pancreatic phospholipase A2 by colipase.

摘要

人乳脂肪球需要在胆汁盐存在的情况下，借助辅脂酶才能被胰脂肪酶水解。这与《临床研究杂志》（J. Clin. Invest. 67: 1748 - 1752.）最近的一篇报道相反，该报道称添加辅脂酶或磷脂酶A2可克服胆汁盐对脂肪酶的抑制作用。后一项发现被证明是由于市售胰磷脂酶A2被辅脂酶污染所致。
