Atsilsglütseroolide
Atsilsglütseroolide, also known as acylglycerols or triglycerides, are esters formed from glycerol and three fatty acids. They are the primary components of body fat in humans and animals, as well as vegetable fat. In this esterification process, the hydroxyl groups of glycerol react with the carboxyl groups of fatty acids, releasing water molecules. The properties of the resulting atsilglütseroolide depend on the specific fatty acids that are attached to the glycerol backbone. Fatty acids can be saturated, meaning they contain no double bonds between carbon atoms, or unsaturated, containing one or more double bonds. The length of the fatty acid chain also influences the physical properties, such as melting point. For example, triglycerides with shorter, unsaturated fatty acid chains tend to be liquid at room temperature (oils), while those with longer, saturated fatty acid chains are typically solid (fats). Atsilsglütseroolide serve as a major form of energy storage in living organisms, providing a concentrated source of calories. They are also important for insulation and the protection of organs. In the digestive system, atsilglütseroolide are broken down into glycerol and fatty acids for absorption and utilization by the body.
