谷物及其加工品脂肪酶解的生化机制

摘要

The major pathways of lipid degradation in cereal grains are by hydrolytic or oxidative reactions,or by a combi-nation of both. The review described the distribution of triglyceride lipase,lipid acyl hydrolases (LAH) within cereal grains and their physiological aspects,and the mechanism for enzymic degradation of lipids. The newly analysis of oxylipin path-way will be useful to elucidate the quality deterioration of cereal grains and their products.%　　谷物粮食的脂肪降解方式是水解和氧化反应。总结了谷物三酰甘油(TG)脂肪酶、脂肪酰基水解酶(LAH)在谷物籽粒中的活性分布、生理作用，以及脂肪酶解的生化机制。并指出氧脂途径的分析对谷物及其加工品品质劣变机理的了解有指导意义。
