Lipogenesis is the process by which acetyl-CoA is converted to fats. The former is an intermediate stage in metabolism of simple sugars, such as glucose, a source of energy of living organisms. Through lipogenesis, the energy can be efficiently stored in the form of fats. Lipogenesis encompasses the processes of fatty acid synthesis and subsequent triglyceride synthesis. The products are secreted from the liver in the form of very-low-density lipoproteins (VLDL).
