Detailed explanation-1: -In a pleated sheet, two or more segments of a polypeptide chain line up next to each other, forming a sheet-like structure held together by hydrogen bonds. The hydrogen bonds form between carbonyl and amino groups of backbone, while the R groups extend above and below the plane of the sheet 3.
Detailed explanation-2: --Sheets consist of extended polypeptide strands (-strands) connected by a network of hydrogen bonds and occur widely in proteins.
Detailed explanation-3: -So, the correct answer is, ‘Linking together two or more polypeptide chains.
Detailed explanation-4: -What is a beta-pleated sheet of protein? Beta-Pleated Sheets of Protein is a type of secondary structure of a protein. It consists of various beta strands linked by hydrogen bonds between adjacent strands. Three to ten amino acids are combined to create a beta-strand polypeptide.
Detailed explanation-5: -In a beta-sheet two or more polypeptide chains run alongside each other and are linked in a regular manner by hydrogen bonds between the main chain C=O. and N-H groups. Therefore all hydrogen bonds in a beta-sheet are between different segments of polypeptide.
