Synopsis of Regulatory Mechanisms in Fat Metabolism

Situations in which the blood insulin/glucagon ratio is higher than normal lead to fatty acid and cholesterol biosynthesis, whereas low insulin/glucagon ratios are characterized by lipolysis, increased activity of the /3-oxidation pathway, and a low level of cholesterol biosynthetic activity. Enzymes that are either activated by insulin or derepressed by low glucagon levels are lipoprotein lipase, which
