Lippincott's - Ch. 24

Question:
What happens to the surplus amino acids?
Answer:
They are not stored, but are either released into the blood for all tissues to use in protein synthesis or are deaminated, with the resulting carbon skeletons being degraded by the liver to pyruvate, acetyl CoA, or TCA cycle intermediates. These metabolites can be oxidized for energy or used in fatty acid synthesis.
