GlucogenicandKetogenicAminoAcids
A significant amount of metabolic energy can come from amino acid metabolism, particularly under conditions of starvation. The metabolism of amino acids occurs through common metabolic intermediates, many of them part of or linked to the Krebs cycle. The intermediates like pyruvate, oxaloacetate, fumarate, succinyl-CoA and alpha-ketobutyrate all can contribute to the net synthesis of glucose through gluconeogenesis. ......閱讀全文
