Amino acids, the building blocks of proteins, have the ability to act as buffers in the body. This means that proteins can maintain normal blood pH. By maintaining normal blood pH, the body's proteins are protected from being what?
A) Neutralized B) Naturalized C) Deneutralized D) Denatured
D
Feedback:
Because amino acids contain both an acid (COOH) and a base (NH2), they can act as either acids or bases depending on the pH of the surrounding fluid. The ability to buffer or neutralize excess acids and bases enables proteins to maintain normal blood pH, which protects body proteins from being denatured. Proteins are not neutralized, naturalized, or deneutralized.
