Question

Quizplus · Accepted Answer

Excess amino acids consumed through protein supplements will undergo deamination in the liver, where the amino group is removed and turned into ammonia. The remaining carbon skeleton can then be used for energy or stored as fat. Without sufficient exercise to build muscle tissue, the excess amino acids cannot be added to her muscle tissue. Additionally, protein metabolism requires calcium, but excess amino acids will not enhance the body's absorption of calcium.
