| Description | Stearoyl-CoA is a long-chain acyl CoA ester that acts as an intermediate metabolite in the biosynthesis of monounsaturated fatty acids; a critical committed step in the reaction is the introduction of the cis-configuration double bond into acyl-CoAs (between carbons 9 and 10). This oxidative reaction is catalyzed by the iron-containing, microsomal enzyme, stearoyl-CoA desaturase (SCD, EC 1.14.19.1). NADH supplies the reducing equivalents for the reaction, the flavoprotein is cytochrome b5-reductase and the electron carrier is the heme protein cytochrome b5. Stearoyl-CoA is converted into oleoyl-CoA and then used as a major substrate for the synthesis of various kinds of lipids including phospholipids, triglycerides, cholesteryl esters and wax esters. Oleic acid is the preferred substrate for acyl-CoA cholesterol acyltransferase (ACAT, EC 2.3.1.26) and diacylglycerol acyltransferase (DGAT, EC 2.3.1.20), the enzymes responsible for cholesteryl esters and triglycerides synthesis, respectively. In addition oleate is the major monounsaturated fatty acid in human adipose tissue and in the phospholipid of the red-blood-cell membrane. In the biosynthesis of sphinganine, stearoyl-CoA proceeds through the acyl-CoA + serine -> 3-keto-sphinganine -> sphinganine pathway, with the key enzyme being acyl-CoA serine acyltransferase (EC 2.3.1.50) to yield C20-(3-ketosphinganine) long-chain base. There is growing recognition that acyl-CoA esters could act as signaling molecules in cellular metabolism.
