Sterculic oil reduces tissue desaturase indices. Desaturase indices (a) 16 : 1/16 : 0 and (b) 18 : 1/18 : 0 of liver, gonadal adipose (GAT), and subcutaneous adipose (SAT) tissues from wild-type (WT) and ob/ob (OB) mice receiving an AIN-93G diet (AIN) or a sterculic oil-supplemented diet (SO). Data are presented as means SE; per group. Data were analyzed by two-way ANOVA and significance for the effects of diet (d), genotype (g), or their interaction () set at . When a significant interaction effect was found a Bonferroni multiple comparisons test was used to determine differences within groups. WT AIN versus WT SO; OB AIN versus OB SO.
