WebWhen fatty acid levels are elevated and exceed the metabolic capacity of the TCA cycle, acetyl-CoA is shunted to ketogenesis. Two acetyl-CoAs can combine through a thiolase enzyme to produce acetoacetyl-CoA, which is a precursor for the synthesis of acetoacetate (ACA) and β-hydroxybutyrate (BHB). WebFeb 8, 2024 · Also, p53 increases acetyl-CoA production by enhancing fatty acid oxidation [44, 45] and suppressing lipid synthesis , thereby boosting the initiation of the TCA cycle. Glutamine, an important source of nutrients in the TCA cycle, is converted to glutamate and subsequently to α-ketoglutarate. p53 promotes the conversion of glutamine into ...
