人乳蛋白质可提供氮、酶,激素及免疫物质,对婴儿的健康成长有重要作用。人乳纯蛋白(非蛋白氮除外)含量约为1.0g/100ml,酪蛋白和乳清蛋白为人乳蛋白的两种主要成分。人乳酪蛋白均为β-和K-型酪蛋白,而无α-型酪蛋白。此外还有α-乳白蛋白、乳铁蛋白、血清白蛋白及溶菌酶和免疫球蛋白、人乳不含β-乳球蛋白,这点与牛乳不同。为了解人乳中各种蛋白质成分在哺乳期间的变化,本研究采用多聚
Human milk protein can provide nitrogen, enzymes, hormones and immune substances, the healthy growth of infants play an important role. Human milk pure protein (except for non-protein nitrogen) content of about 1.0g / 100ml, casein and whey protein are two main components of human milk protein. Human milk caseins are both beta- and K-type casein, but not alpha-type casein. In addition there are α-lactalbumin, lactoferrin, serum albumin and lysozyme and immunoglobulin, human milk does not contain β-lactoglobulin, which is different from milk. In order to understand the changes of various protein components in human milk during breast-feeding, the study used poly-mers
