WebThe alanine amino acid acts as a shuttle - it leaves the cell, entering the blood stream and traveling to hepatocytes in the liver, where essentially this entire process is reversed. Alanine undergoes a transamination reaction with free α-ketoglutarate to yield glutamate, which is then deaminated to form pyruvate and, ultimately, free ammonium ion. WebExcess amino acids absorbed in the blood that are not needed to make proteins cannot be stored, so they are broken down in a process called deamination. The amino group of all amino acids - NH 2 (which contains the nitrogen atoms) is removed, hence the term de- amin (o) -ation. Enzymes in the liver split up the amino acid molecules.
