摘要
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毛高约3%,但组氨酸和胱氨酸含量仅为绒毛的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:藏羚羊绒毛的组氨酸含量为5.88%,比山羊绒和绵羊毛高约4%;胱氨酸含量为10.60%,高于其他所测山羊的绒和毛;碱性氨基酸与酸性氨基酸含量接近(14.87%,15.23%);藏羚羊绒毛促螺旋蛋白(Paa)含量低于降螺旋蛋白(Daa)。
Amino acid contents in cashmere and shatooh of Tibetan antelope were analyzed.The content of the glutamic acid in shatoosh was 3% higher then in cashmere, while histidine and cystine in shatoosh were 66% and 15.48% respectively of their contents in cashmere.Amino acids of proteins in sheep and goat fur were same as those in Tibetan antelope, yet contents of different amino acids were different： the content of histidine in cashmere was 5.88% ,4% higher than that in goat and sheep wool; the content of cysfine was 10.60%, higher than that in goat and sheep; basic and acidic amino acids were nearly the same, being 14.8% and 15.23% respectively; the content of Paa in cashmere was lower than that of Daa.
