BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Peptide bonds and disulfide bonds form the primary structure of proteins.

Detailed explanation-2: -The primary protein structure refers to the sequence of amino acids and the location of disulfide bonds (Figure 10). The amino acids, when linked by peptide bonds, are referred to as residues.

Detailed explanation-3: -Disulfide bonds make proteins less susceptible to unfolding; typically, they will link-sheets, -helices, and loops, which means that they primarily maintain tertiary structure, not secondary, which refers to local conformations, and is maintained largely by hydrogen bonds.

Detailed explanation-4: -The primary structure is comprised of a linear chain of amino acids. The secondary structure contains regions of amino acid chains that are stabilized by hydrogen bonds from the polypeptide backbone. These hydrogen bonds create alpha-helix and beta-pleated sheets of the secondary structure.

Detailed explanation-5: -Peptide Bonds The primary structure of a protein consists of amino acids chained to each other. Amino acids are joined by peptide bonds. A peptide bond is a type of covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid.
