Indicators
A family of pyridoxal phosphate-dependent enzymes involved in cellular nitrogen metabolism, amino acid metabolism, and liver gluconeogenesis. Alanine aminotransferase specifically and reversibly catalyzes the transfer of an amino group from L-alanine to alpha-ketoglutarate forming pyruvate and L-glutamate.
Indicators
A family of pyridoxal phosphate-dependent enzymes involved in amino acid metabolism and in the urea and tricarboxylic acid cycles. Aspartate aminotransferase specifically and reversibly catalyzes the transfer of an amino group from L-aspartate to alpha-ketoglutarate forming oxaloacetate and L-glutamate.
Indicators
A collective term for pteroylglutamic acids and their oligoglutamic acid conjugates. As a natural water-soluble substance, folic acid is involved in carbon transfer reactions of amino acid metabolism, in addition to purine and pyrimidine synthesis, and is essential for hematopoiesis and red blood cell production. (NCI05)
Indicators
GGT participates in the transfer of amino acids across the cellular membrane and in glutathione metabolism. High concentrations are found in the liver, bile ducts, and the kidney. A test that measures the amount of GGT in the blood is used to detect diseases of the liver, bile ducts, and kidney; and to differentiate liver or bile duct (hepatobiliary) disorders from bone disease.
