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

Question 2

The nurse is conducting a support group with clients who have CKD. Today's topic is concerning the various types of protein and the reasons for consuming one over the other.
 
  The nurse discusses the rationale for using high biologic proteins instead of low biologic proteins is related to which of the following reasons? A) Contain less nitrogen and therefore minimize urea production
  B) Contain more fat and therefore more calories to minimize body protein catabolism
  C) Promote reuse of circulating nonessential amino acids for protein synthesis and therefore minimize urea production
  D) Are the only type of protein used for protein synthesis

Answer to Question 1

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.

Answer to Question 2

C
Feedback:
High biologic value proteins may promote reuse of circulating nonessential amino acids for protein synthesis, and by doing so minimizes urea production.
