transenoyylCoA

TransenoyylCoA is a type of fatty acid derivative that plays a role in metabolism. It is characterized by a double bond in the trans configuration within its acyl chain, attached to Coenzyme A. This specific structure is an intermediate in various metabolic pathways, most notably in the beta-oxidation of unsaturated fatty acids.

During the breakdown of unsaturated fatty acids, enzymes called acyl-CoA dehydrogenases introduce double bonds. When these double bonds are initially in the trans configuration, they can be processed directly by the standard beta-oxidation machinery. However, if the double bond is in the cis configuration, it requires enzymatic isomerization to the trans form before further oxidation can occur. TransenoyylCoA, therefore, represents a substrate that is readily processed by enoyl-CoA hydratase, the next enzyme in the beta-oxidation pathway.

The presence and metabolism of transenoyylCoA are crucial for the efficient energy extraction from dietary and endogenous unsaturated fats. Disruptions in the enzymes involved in its formation or processing can lead to metabolic disorders. It is a transient molecule, meaning it is quickly converted into other metabolic intermediates.
