However, while processes that regulate lipid droplets such as lipolysis and lipogenesis are relatively well known, the major factors that control lipophagy remain largely unknown. This review lipogenesis: synthesis of lipids that occurs in the liver or adipose tissues. lipolysis: breakdown of triglycerides into glycerol and fatty acids. monoglyceride molecules: lipid consisting of a single fatty acid chain attached to a glycerol backbone. pancreatic lipases: enzymes released from the pancreas that digest lipids in the diet ance between lipogenesis, lipid uptake and intracellular lipolysis would, therefore, be required to maintain lipid homeostasis [47] .

For example, stimulatory hormones like, epinephrine, norepinephrine, cortisol, glucagon, and growth hormone induce lipolysis. Lipogenesis is the metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. The triglycerides in fat are packaged within cytoplasmic lipid droplets. The process begins with acetyl-CoA, which is an organic compound used to transfer energy from metabolism of carbohydrates , fatty acids , and ethanol . Dietary lipid levels affect lipoprotein clearance, fatty acid transport, lipogenesis and lipolysis at the transcriptional level in muscle and adipose tissue of large yellow croaker (Larimichthys crocea ) Lipogenesis increased by 375% under mild hypoxia, but dropped by 43% in severe hypoxia. Mild, but not severe, hypoxia increased formation of large lipid droplets 6.4 fold and strongly induced gene expression of adipocyte-specific markers. Spontaneous lipolysis increased by 488% in mild, but only by 135% in severe hypoxia.

Both occur in adipocytes. Both are associated with lipotoxicity.

Fat accumulation is determined by the balance between fat synthesis (lipogenesis) and fat breakdown (lipolysis/fatty acid  We studied lipogenesis and lipolysis of omental adipocytes from obese (OB) and non-obese (NOB) humans.

Lipogenesis is the process that converts sugars to fats, which are subsequently deposited and stored in fat tissue. Two opposing forces determine the amount of fat you carry around from day to day.

Increased whole body energy expenditure and protection

Upon energy demand WAT lipolytic pathways are activated to hydrolyze triacylglycerol into glycerol and free fatty acids (FFAs) to release energy for the body [14]. Fat build-up is determined by the balance between lipogenesis and lipolysis/fatty acid oxidation. In the past few years, our understanding of the nutritional, hormonal and particularly transcriptional regulation of lipogenesis has expanded greatly.
