摘要: Hydrolysis of tricaprylin by pancreatic lipase resulted in a stepwise hydrolysis, triglyceride to diglyceride monoglyceride, as has been obtained with long-chain triglycerides. However, hydrolysis rates were much faster and considerable amounts free glycerol formed. an equimolar mixture triolein indicated that some the short-chain fatty acid was released from 2-position before all oleic 1-position. genuine randomized milk fat preferential glycerides containing acids. This phenomenon not dependent on specific distribution these acids, since it also occurred fat. It concluded part acids is located 2-position. The caprylic capric between 1- 2-positions approximately at random. Lauric, myristic, palmitic are predominantly 2...
