Stearoyl-CoA desaturase-1 (SCD1) is a microsomal enzyme that regulates the conversion of SFA (palmitic [16∶0] and stearic acid [18∶0]) into MUFA (palmitoleic [16∶1] and oleic acid [18∶1], respectively) [14]–[16] (Figure 1) and is suggested to play an important role in cancer progression [17]. This evidence concerns the gene SCD and cancer.
