Keratin beta pleated sheet

Webβ-Keratin (Fig. 2b) or fibroin, the major protein in silk, has a pleated sheet structure where identical or opposed molecular strand alignments make up parallel or antiparallel beta … WebThe alpha helix has a right-handed spiral conformation. It is a polypeptide chain that is rod-shaped and coiled in a spring-like structure. Beta pleated sheets are made of beta strands connected laterally by two or more hydrogen bonds. Each beta strand is made up of 3 to 10 amino acid residues. Hence, the correct answer is 'Secondary structure'.
