Producing Keratin Hydrolysates from Sheep Wool
Manuscript describes producing keratin hydrolysate from sheep wool through two-stage technology whose principle consists in first having wool processed in an alkaline environment during the first stage, and then effecting hydrolysis in the second stage through the action of proteolytic enzyme. Experiments were planned in accordance with factor schemes of 23 types in which factors under study we...
متن کاملWool Keratin-Associated Protein Genes in Sheep—A Review
The importance of sheep's wool in making textiles has inspired extensive research into its structure and the underlying genetics since the 1960s. Wool keratin-associated proteins (KAPs) are a key structural component of the wool fibre. The characterisation of the genes encoding these proteins has progressed rapidly with advances in the nucleotide and protein sequencing. This review describes ou...
متن کاملKeratin Coatings for Wool: Shrinkproofing and Nanoparticle Delivery
Wool fabrics were treated with keratin hydrolysate in isolated systems, in systems incorporating a cross-linking enzyme, and in systems with nanoparticle silver. The dimensions of wool fabric were controlled after keratin applications and the strength of bleached wool fabric was improved. Keratin applications imparted these improved properties when applied alone and when applied with the enzyme...
متن کاملReaction of [60]fullerene with trans-epoxides: a theoretical study.
The experimental results of the reaction of C60 with carbonyl ylides generated from trans-epoxides, which afforded cis-products exclusively or predominantly, can be explained well by computational investigation of the proposed reaction mechanism. Our theoretical calculations demonstrate that only cis-carbonyl ylides can be formed directly from trans-epoxides, in compliance with the Woodward-Hof...
متن کاملNature of the Reaction of Wool with Alkali
The course of the reaction of the cystine in wool with alkali has been reinvestigated. The earlier findings that one sulfur atom is split from each molecule of cystine are confirmed. Of the residual noncystine sulfur in the alka li-tregted wool, mbre than 25 percent has been accounted for as lanthionine. No signifi cant amounts of sulfhydryl groups are in the t reated wools. The results lead to...
