WebAug 13, 2024 · Biotin (B 7) Biotin (water-soluble vitamin) is required as a coenzyme in the citric acid cycle and in lipid metabolism. It is also required as an enzyme in the synthesis of glucose, fatty acids, and some nonessential amino acids and carries carbon dioxide (CO 2) away from the citric acid cycle (TCA cycle). A specific enzyme, biotinidase, is ... WebIn biochemistry and metabolism, beta oxidation (also β-oxidation) is the catabolic process by which fatty acid molecules are broken down [1] in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH 2, which are co-enzymes used in the electron transport chain. WebHere we show that in rats and cultured cells it is the result of reduced TCA cycle flow, partly due to deficient anaplerotic biotin-dependent pyruvate carboxylase.
