WebThe enzyme alanine transaminase, or ALT, removes an amino group from alanine, and turns it into pyruvate. The amino group attaches to an acid called alpha ketoglutarate, which then turns into glutamate. And in general, transaminase enzymes require pyridoxine, or vitamin B6 as a cofactor. WebThe difference includes amino acid metabolisms (glutamine, glutamate, alanine, glutathione and other amino acids, see Table 2) and nitrogen metabolism. In contrast, pathways on the left side of Figure 5 including glycolysis/gluconeogenesis and pyruvate metabolism reflect the transcriptomic responses. These pathways contain fructose and mannose ...
