介绍了角蛋白的来源、分类、化学组成与分子结构,以及毛发的宏观形态、微观结构及组成.目前从毛发和羽毛中提取角蛋白常用机械法、化学法和生物法等,其中化学法又可分为酸碱水解法、还原法、氧化法等,分析了各提取方法在提取率、分子量等方面的差异.除水解产物用作饲料外,由于自身特殊的结构和性能,使得角蛋白在生物相容材料、纺丝材料等等方面的应用受到关注.

The sources, composition and structures of keratin were introduced. The pattern, macroscopic structures and composition of hairs and feather were discussed too. The methods for extracting keratin from hairs and feather were summarized. The typical chemical methods are acid-base hydrolysis, reduction and oxidation. The molecular weight and yield of keratin were analyzed. The keratin and its derivatives were applied to feed, hairdressing and medicine. Its applications in materials and biomedicine have also been developing.
