Synthesis of Two Peptide Mimetics as Markers for Chemical Changes of Wool's Keratin During Skin Unhairing Process
Abstract:The sheep skins unhairing process with preliminary alkaline treatment of the wool leads to two unnatural dipeptide mimetics lysinoalanine (Lys* - Ala) and ornithinoalanine (Orn*- Ala) obtaining. They are result from the keratin hydrolysis process. The changes of wool keratin make it resistant to sulphide degradation. We synthesized and characterized these unnatural dipeptides under the experimental conditions. The structures and mechanism of Lys* - Ala and Orn*- Ala obtaining were elucidated. The using of newly synthesized products as markers for control of wool's keratin changes during skin unhairing process was demonstrated. The developments have also been the result of economic and environmental pressures to meet environmental regulations.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
