SCD and Insulin resistance: Other reported markers of insulin resistance or T2D primarily from cross-sectional studies include increased fasting blood or urine stearoyl-CoA desaturase-derived fatty acids, glucose derivatives and gluconeogenic precursors, bile acids or derivatives, cystine-cysteine (e.g., [5], [7], [8], [15], [16], [69], [70]), and decreased glycine, glutamine, L-GPC, and arachidonic acid (e.g., [5], [7]–[9], [13], [15], [16], [71]).
