How Do Properties of Amino Acids Affect the Function of Proteins

How do properties of amino acids affect the function of proteins?

A) Amino acids vary in their chemical side chains,and interactions among side chains affect the protein folding that determines protein shape and function.
B) Amino acid side chains link individual amino acids to form linear protein molecules,allowing amine and carboxyl groups to determine protein shape and function.
C) Amino acids vary in how much adenine,cytosine,thymine,and guanine are present,and these differences affect the protein folding that determines protein function.
D) Amino acid side chains have active and inactive forms,and the pattern of active and inactive side chains determines how the protein folds and functions.
E) Amino acids vary in the structure of their amine and carboxyl groups,and interactions among these functional groups affect protein folding and function.
