Dietary Amino Acids in a Meal That are in Excess

Question

Dietary amino acids in a meal that are in excess of the body's need to make protein are
A)converted to glucose in the liver.
B)converted to fatty acids in the liver. 
C)excreted without being absorbed.
D)converted to fatty acids in adipose cells.
E)burned for fuel by cells of the nervous system.

Accepted Answer

Excess dietary amino acids are deaminated and the remaining carbon skeleton can be converted into glucose, fatty acids or ketone bodies. The liver converts the carbon skeleton of amino acids into fatty acids, which can be stored in adipose tissue or released into the bloodstream for energy production. Therefore, excess dietary amino acids can be converted to fatty acids in the liver.
