Stearoyl-CoA desaturase 5 (SCD5)

Stearyl-CoA desaturase that utilizes O(2) and electrons from reduced cytochrome b5 to introduce the first double bond to saturated fatty acyl-CoA substrates. Catalyzes the insertion of a cis double bond in the delta-9 place into fatty acyl-CoA substrates including palmitoyl-CoA and stearoyl-CoA (PubMed:15907797, PubMed:15610069).

Gives rise to a mixture of 16:1 and 18:1 unsaturated fatty acids. .
