Indicators of stearoyl-CoA desaturase (SCD  =  ∆9-desaturase) activity, that is, the palmitoleic:palmitic acid (0.2) and oleic:stearic acid (1.5) ratios, were higher, while the PUFA:SFA ratio (0.6) was lower in HBV-related cirrhosis patients than in control subjects [61]. The gene discussed is SCD; the disease is Cirrhosis.
