The Metabolic Destiny of Propionyl-CoA: Exploring the Interconversion of Propionate and Acetyl-CoA

Propionyl-CoA is an intermediate molecule within the oxidation of fatty acids with odd numbers of carbons. It’s a three-carbon molecule that’s the precursor of both propionate or acetyl-CoA. Propionate can be utilized within the synthesis of glucose, whereas acetyl-CoA is used to provide power by way of the Krebs cycle. The metabolic destiny of propionyl-CoA is decided by a collection of enzymatic reactions involving the propionyl-CoA carboxylase and the methylmalonyl-CoA mutase enzymes, each of that are a part of the mitochondrial matrix (Santos et al., 2016). The propionyl-CoA carboxylase enzyme catalyzes the response that converts propionyl-CoA to methylmalonyl-CoA. Methylmalonyl-CoA is then isomerized to succinyl-CoA by the methylmalonyl-CoA mutase enzyme, which then enters the Krebs cycle (Lam and Schuster, 2020). Alternatively, propionate might be fashioned from propionyl-CoA because of a response catalyzed by the biotin-containing enzyme propionyl-CoA carboxylase. The oxidation of fatty acids with odd numbers of carbons in the end produces an intermediate with three carbons referred to as propionyl-CoA. This response is catalyzed by the mitochondrial enzyme propionyl-CoA carboxy-lyase (PCCL) and is a crucial step in fatty acid and power metabolism. The subsequent step in metabolism is to transform propionyl-CoA into both succinyl-CoA or methylmalonyl-CoA. Cont….
