Alanine catabolism

WebAlanine transports amino groups (from protein degradation) and carbons from the skeletal muscles to the liver during a fasting state. The liver takes up the alanine and converts it back into pyruvate via ALT, which is used for gluconeogenesis. Urea (from amino groups) is a byproduct. Stimulated by: ↑ NADH / NAD + ratio. Anaerobic states (e.g ... WebAug 1, 1998 · Alanine is an important nitrogenous product of the intestinal catabolism of glutamine, glutamate, aspartate ( Windmueller 1982) and perhaps BCAA. Thus, alanine transaminase appears to function primarily for alanine synthesis in intestinal mucosa. Alanine may serve to transport nitrogen of some dietary amino acids to extraintestinal …
