甘油二酯的合成、代谢及应用研究进展

甘油二酯是油脂代谢的中间产物，是一种重要的功能油脂，也是国际公认安全的食品成分。根据脂肪酸酰基与甘油骨架上羟基连接位置不同，甘油二酯分为1，3-甘油二酯、1，2-甘油二酯和2，3-甘油二酯三种异构体，其中1，2-甘油二酯和2，3-甘油二酯互为同分异构体。目前国内外多项研究表明甘油二酯特别是1，3-甘油二酯具有抑制脂肪积累和降低血脂的功能。因此，甘油二酯已被广泛应用于医药、食品、化工等工业领域中，具有良好的商业价值。本文主要介绍了甘油二酯的代谢、合成、检测、应用现状及伴随产生的食用安全性，并讨论了甘油二酯未来的研究方向，以期为甘油二酯的进一步研究提供参考。

Research Progress on Synthesis, Metabolism and Application of Diglycerides

Diglyceride is an intermediate product of lipid metabolism, an important functional lipid, and an internationally recognized safe food ingredient. DAG is divided into three isomers, 1,3-diglyceride, 1,2-diglyceride and 2,3-diglyceride, according to the different connecting positions of fatty acid acyl groups and hydroxyl groups on the glycerol backbone. Among them, 1,2-glycerol Diesters and 2,3-diglycerides are isomers of each other and no distinction is made between them. At present, many studies at home and abroad have shown that diglycerides, especially 1,3-diglycerides, have the functions of inhibiting fat accumulation and reducing blood lipids. Therefore, diglycerides have been widely used in pharmaceutical, food, chemical and other industrial fields, and have good commercial value. This article mainly introduces the metabolism, synthesis, detection, application status of diglycerides and the accompanying edible safety, and discusses the future research direction of diglycerides, in order to provide references for further research on diglycerides
