BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity.

Detailed explanation-2: -Because amino acids can be arranged in many different combinations, it’s possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.

Detailed explanation-3: -Protein structures are made by condensation of amino acids forming peptide bonds. The sequence of amino acids in a protein is called its primary structure. The secondary structure is determined by the dihedral angles of the peptide bonds, the tertiary structure by the folding of protein chains in space.
