Lipid class

Triacylglycerol

Description
placeholder: Triacylglycerols, also known as triglycerides, are a class of neutral lipids composed of a glycerol backbone esterified with three fatty acid chains. The glycerol molecule, a three-carbon sugar, serves as the backbone, while the fatty acid chains, typically ranging from 16 to 24 carbons in length, are attached to the glycerol through ester linkages. The function of triacylglycerols is primarily energy storage, as they are the main component of adipose tissue, where they are stored in lipid droplets. Upon lipolysis, triacylglycerols are broken down into fatty acids and glycerol, which can then be utilized by the body as energy sources or building blocks for other lipids. Additionally, triacylglycerols play a role in the absorption and transport of dietary fats, as they are the primary form in which fats are absorbed from the gut and transported through the bloodstream.
