Detailed explanation-1: -Hydrogen bonds in a protein molecule. Large numbers of hydrogen bonds form between adjacent regions of the folded polypeptide chain and help stabilize its three-dimensional shape.
Detailed explanation-2: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.
Detailed explanation-3: -This three-dimensional shape is held in place by hydrogen bonds. A hydrogen bond is a dipole-dipole interaction between a hydrogen atom and an electronegative atom, such as nitrogen or oxygen. A single polypeptide chain may contain multiple alpha-helix and beta-pleated sheet regions.
Detailed explanation-4: -Proteins are the polymers of amino acids. Amino acids are joined together by a special type of covalent bond (peptide bond) to form linear structures called polypeptides.
Detailed explanation-5: -Hydrogen bonds provide most of the directional interactions that underpin protein folding, protein structure and molecular recognition. The core of most protein structures is composed of secondary structures such as helix and sheet.
