Fasting serum free glycerol concentration is a potential surrogate marker of visceral obesity and insulin sensitivity in middle-aged Japanese men

Triglyceride (TG) is a tri-ester composed of a glycerol and three fatty acids. Degradation of TG in adipose tissue is increased in the fasting state, but inhibited in the postprandial state. Although insulin suppresses adipose TG degradation, patients with insulin resistance have high concentrations of insulin and free glycerol (FG) in the fasting state.
