WebThe 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.

The beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet. A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with backbone in an extended conformation.

WebMyoglobin DNA polymerase Correct answer: Myoglobin Explanation: Quaternary structure of a protein involves the assembly of subunits. Hemoglobin, p53 and DNA polymerase are all composed of subunits, while myoglobin is a functional single sequence. Since myoglobin does not have multiple subunits, it does not have quaternary structure. WebDec 11, 2024 · The other common secondary structure is the beta-pleated sheet. In this structure, two different regions of a polypeptide chain lie side by side and are bound by hydrogen bonds. They make up the core of many globular proteins. The two types of beta-pleated sheets are parallel beta-pleated sheets and antiparallel beta-pleated sheets.
