Title: KERATIN DERIVATIVE OBTAINABLE AT HIGH YIELD, AND METHOD OF USING SAME
Abstract:
Provided is a keratin derivative having especially high yield and reduced denatured protein content, and a method of using the same. This keratin derivative is obtained, without using excessive chemical agents, from hair from which the surface cuticle, which is resistant to dissolution, decomposition, and conversion to derivatives, has been partially or entirely removed. In particular, aminoethyl disulfide keratin, in which some or all of the disulfide bonds (-S-S-) are easily converted to aminoethyl disulfide groups by aminoethanethiol, is a desirable keratin derivative in terms of stability and solubility. In addition, the keratin derivative can be obtained at high yield, contains little denatured keratin, and can be inexpensively formed into artificial blood vessels, surgical suture, wound dressing sheets, artificial tortoiseshell, artificial ivory, artificial leather, wool nanofibers, and the like.
