摘要: 作者对藏羚羊被毛纤维氨基酸含量进行了测定,结果表明,藏羚羊粗毛中谷氨酸含量比绒纤维的提高32.5%,但组氨酸和胱氨酸含量仅为绒纤维的66%和15.48%。藏羚羊被毛角蛋白氨基酸的组成与山羊、绵羊被毛纤维相同;但在各种氨基酸的含量比例上有一定的差异,藏羚羊绒组氨酸含量为5.88%,均高于山羊绒和绵羊毛中组氨酸的含量;胱氨酸含量为10.60%,高于其它所测山羊的绒和毛;碱性氨基酸与酸性氨基酸含量接近(14.87%,15.23%);藏羚羊绒促螺旋蛋白(Paa)含量低于降螺旋蛋白(Daa)。

Abstract: The component of α protein of Shatoosh fibre and hair were composed of 20 kinds of amino acids, same as other wool or cashmere, but the content of each amino acid was different. The content of glutamic acid in Shatoosh fibre was 3 percents higher than which was in the hair, while Histidine and Cystine were only 66% and 15.48% to the hair. The content of Histidine in Shatoosh fibre was 5.88%, which was 4 percents higher than other wool or cashmere. The content of Cystine was 10.60%, the highest among experimental samples, which would be embodied the excellent fiber quality and textile performance.The amount of alkali amino acid was close to acid amino acid was found in Shatoosh, which suggested that Shatoosh has strong capbility to resist alkali and acid solution, microorganism etal. The ratio of Paa to Daa was less than 1, which confirmed the point came from alkali and acid amino acid again.
