摘　　要：除了反应条件温和以及具生物可降解性等酶类的共同优点之外,脂肪酶所具有的各类选择性使其成为应用最广泛的生物催化剂之一。由于脂肪酸的位置分布能显著影响甘油三酯的营养学价值和物理化学性质,因此脂肪酶的位置选择性成为功能性结构甘油三酯合成领域最受关注的特性。文章首先从分类、分析方法和影响因素等方面对脂肪酶的位置选择性进行综述,进而详细介绍了脂肪酶位置选择性在类可可脂与可可脂改良剂、人母乳脂肪替代品以及MLM型结构酯等功能性结构甘油三酯合成中的应用。Various selectivities make lipases become one of the most widely used biocatalysts,besides common advantages of enzymes including mild reaction conditions and biodegradability.Since positional distribution of fatty acids can significantly affect the nutritive value and physicochemical properties of triacylglycerols,lipase regioselectivity has become the major concern in the field of synthesis of functional structured triacylglycerols.This paper reviewed the progress of lipase regioselectivity in the aspects of classification,analysis methods and influence factors.Moreover,applications of regioselectivity in synthesis of functional structured triacylglycerols were particularly introduced,such as cocoa butter equivalents and improvers,human milk fat substitutes and MLM type structured lipids.
