Several indicators were associated with the worsening of hyperglycemia: palmitoleic acid, dihomo-γ-linolenic acid, ratio of palmitoleic acid (16:1n–7) to palmitic acid (16:0) as a marker of stearoyl coenzyme A desaturase 1 activity and the ratio of dihomo-γ-linolenic acid (20:3n−6) to linoleic acid (18:2n−6) as a marker of delta 6 desaturase activity. The gene discussed is FADS2; the disease is Hyperglycemia.
