BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Silk fibroin is composed of -sheet crystallites (hereafter simply referred to as crystallites) and amorphous domains [2, 3].

Detailed explanation-2: -The secondary structure of silk is the beta pleated sheet. The primary structure of silk contains the amino acids of glycine, alanine, serine, in specific repeating pattern. These three amino acids make up 90% of the protein in silk. The last 10% is comprised of the amino acids glutamic acid, valine, and aspartic acid.

Detailed explanation-3: -The heavy fibroin protein consists of layers of antiparallel beta sheets. Its primary structure mainly consists of the recurrent amino acid sequence (Gly-Ser-Gly-Ala-Gly-Ala)n.

Detailed explanation-4: -It consists of several monomers arranged together in a three-dimensional space. Thus, based on the above information we can conclude that a
