乳脂肪酸及其影响因素的研究进展

Milk Fatty Acids and its Influencing Factors

脂肪酸在生命活动中具有非常重要的作用,而乳是许多脂肪酸的天然来源。乳中脂肪酸既可以由乳腺从头合成,也可直接来自于血液,这个过程受遗传、饲料、泌乳阶段、年龄、季节、养殖方式、畜群效应等多方面因素的影响。作者介绍了乳中脂肪酸的合成及各脂肪酸间的相关性,并对影响脂肪酸组成各种因素进行了综述。

Milk is a natural source of kinds of fatty acids,which play important roles in the process of metabolism.FA in milk originated from de novo synthesis in mammary gland and blood directly.It varied with many factors,such as genetic,feed,lactation stage and age,season,farming,flock effect,etc.This article has reviewed fatty acids synthesis and correlation among them,of course,factors affected FA were also included.
