Stearoyl CoA is a saturated fatty acid metabolite involved in polyunsaturated fatty acid synthesis and the PPAR signaling pathway. Stearoyl CoA is a substrate for the enzyme stearoyl-CoA desaturase. Stearoyl CoA desaturation is the crucial step in unsaturated fatty acid biosynthesis. Stearoyl CoA is converted to oleoyl-CoA by stearoyl-CoA desaturase.
