抄録

The amino acid analysis was carried out in order to clarify the differences in keratin between the body hair and the hoof of horse. A distinctive mark was recognized in the content of amino acid residues between the body hair and the hoof. The contents of Asx, Gly, Ala, Ile, Leu, Tyr and Phe were higher and those of Thr, Ser, Pro and Cys were lower in the hoof than in the hair for all samples examined. Of these amino acids, the difference in the content of Cys was most remarkable, implying that Cys plays an important role in determining the kinds of keratin. Moreover, a comparative analysis of specific amino acids between the body hair and the hoof of 7 horse races implied that the blood relationship might be partly reflected in the amino acid composition. Although several components were fractionated by gel filtration in the keratin solubilized with performic acid, only a wide "smear region" was visualized in the range of molecular weight from 100 kD to 30 kD with SDS gel electrophoresis.
