Stearyl-CoA desaturase that utilizes O(2) and electrons from reduced cytochrome b5 to introduce the first double bond into saturated fatty acyl-CoA substrates. Catalyzes the insertion of a cis double bond at the delta-9 position into fatty acyl-CoA substrates including palmitoyl-CoA and stearoyl-CoA (PubMed:12815040, PubMed:16443825). Required for the biosynthesis of membrane phospholipids, cholesterol esters and triglycerides (By similarity).

Belongs to the fatty acid desaturase type 1 family.
