Abstract: Alpha-lactalbumin (α-LA) is a major protein component of breast milk. Therefore, humanization of α-LA from mammalian milk should be an important part of the study aimed to develop infant formula simulating the major protein components in breast milk. The structure of α-LA is described in terms of amino acid composition and stereostructure in this article. Moreover, the functional characteristics of α-LA and its application in infant formula are also discussed, which is expected to provide useful information for researchers in this field.

Key words: alpha-lactalbumin; functional characteristics; infant formula; application

摘要： α-乳白蛋白是母乳蛋白质的重要成分，α-乳白蛋白的母乳化是婴儿配方乳粉模拟母乳蛋白质研究的重要组 成部分。本文从α-乳白蛋白的氨基酸组成和立体结构两方面介绍α-乳白蛋白的结构，论述α-乳白蛋白的功能特性及 其在婴儿配方乳粉中的应用，为广大婴儿配方乳粉科研工作者提供参考。
