Methylmalonyl-CoA is an intermediate molecule in the metabolism of odd-chain fatty acids and certain amino acids. Its formation and subsequent breakdown are crucial steps in energy production and nutrient processing within the body. Specifically, methylmalonyl-CoA is derived from the catabolism of propionyl-CoA, which in turn arises from the breakdown of valine, isoleucine, threonine, methionine, and odd-numbered fatty acids. The conversion of propionyl-CoA to methylmalonyl-CoA is catalyzed by the enzyme propionyl-CoA carboxylase.
Following its formation, methylmalonyl-CoA undergoes an important isomerization reaction. This reaction is catalyzed by the enzyme
Disruptions in the metabolism of methylmalonyl-CoA, particularly due to deficiencies in vitamin B12 or mutations in
