BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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.

Detailed explanation-2: -Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain.

Detailed explanation-3: -The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.

Detailed explanation-4: -To form polypeptides and proteins, amino acids are joined together by peptide bonds, in which the amino or NH2 of one amino acid bonds to the carboxyl (acid) or COOH group of another amino acid.

Detailed explanation-5: -Explanation: Primary structure consists of amino acids joined by peptide bonds. Peptide bonds are between the alpha-carboxyl of one amino acid, and the alpha-amine of the next amino acid. A peptide bond is an example of an amide bond.
