WebAcetyl- Author Manuscript CoA can be generated in the mitochondria by pyruvate oxidation, fatty acid catabolism, or amino acid degradation. Moreover, acetyl-CoA is a crucial substrate for various reactions, including fatty acid synthesis, cholesterol synthesis, and protein acetylation (Figure 2). WebFrom the citric acid cycle, ketogenic amino acids can be degraded directly from pyruvate into acetyl-CoA, a pyruvate dehydrogenase process (1). After which, they’re further catabolized into acetyl-CoA and acetoacetate, then three ketone bodies, namely, Acetoacetate, Acetone, and β-hydroxybutyrate. ethanoic pronounceWebThe video claims that acetyl-coa from fatty acid oxidation cannot contribute to gluconeogenesis because the pyruvate dehydrogenase step is irreversible.
