Triacylglycerol major energy storage

Where are triacylglycerols stored?

Within all cell types, even those of the brain, triacylglycerols are stored as cytoplasmic ' lipid droplets ' enclosed by a monolayer of phospholipids and hydrophobic proteins such as the perilipins in adipose tissue or oleosins in seeds.

What is triacylglycerol?

Triacylglycerol is the major form of dietary lipid in fats and oils, whether derived from plants or animals. Triacylglycerol is composed of three fatty acids esterified to a glycerol molecule (Figure 4).

What is the role of triacylglycerol in lipid metabolism of neuron?

Triacylglycerol (TAGs) play an unimportant role in lipid metabolism of neuron. Nevertheless, they serve as the reservoir of lipid precursors. Triacylglycerol was generate in the adipose tissue and liver, meanwhile it can also emerge in the heart, brain, skeletal muscle and kidney. The transport of the TAGs to these tissue through the blood flow.

How are triacylglycerols transported through the bloodstream?

Dietary triacylglycerols are transported through the bloodstream in chylomicrons. When a chylomicron encounters the enzyme lipoprotein lipase, triacylglycerols are broken down by hydrolysis into fatty acids and glycerol. These breakdown products then pass through capillary walls to be used for energy by cells or stored in adipose tissue as fat.

Why is triacylglycerol structure important?

Triacylglycerol composition and structure are important in the areas of nutrition, oil stability, and possible physiological effects. Table 4 provides data demonstrating the differences in triacylglycerol structure that are reasonably expected among different varieties of peanuts.

What is a triacylglycerol depot?

Other Functions of Triacylglycerol Depots Subcutaneous depots act as a cushion around joints and serve as insulation against cold in many animals, as is obvious for marine mammals such as seals but perhaps less so for the pig, which is surrounded by a layer of fat.
