Question

Quizplus · Accepted Answer

When protein consumption is in excess of body needs and energy needs are met, the excess amino acid molecules will be deaminated and the nitrogen-containing part will be excreted in urine. The remaining carbon skeleton can either be used for energy immediately or be converted to glucose and stored as glycogen in the liver or muscles. However, if glycogen stores are already full, the carbon skeleton can be converted into fatty acids and stored as fat in adipose tissue. Therefore, the excess energy from amino acids can be stored as glycogen and fat.
