In Fat Synthesis, Glycerol And Fatty Acids Combine To Make Fats Plus Energy
Fats are essential for many biological functions such as energy storage, insulation and forming protective layers. Fats are a form of lipids and are composed of glycerol and fatty acids. Fatty acids are synthesized from acetyl-CoA, an energy intensive process that requires ATP, biotin, Mg++, and Mn++. The process of fat synthesis can also occur from dietary sources, where fatty acids are taken into the body from an outside source. In fat synthesis, glycerol and fatty acids combine together to form triglycerides or triacylglycerides. These molecules are composed of three molecules of fatty acids and one molecule of glycerol.
Triglycerides are then used for energy storage, insulation and to form protective layers in organisms. During the synthesis of triglycerides, a process known as esterification occurs whereby energy is released in the form of ATP molecules. This energy comes from the breakdown of glycerol and fatty acids during the synthesis process. Furthermore, when triglycerides are broken down, energy is also produced in the form of ATP molecules.
In conclusion, in fat synthesis, glycerol and fatty acids combine together to form triglycerides plus energy. The energy produced during fat synthesis and breakdown comes from the esterification of glycerol and fatty acids. Triglycerides are then used for energy storage, insulation and forming protective layers in organisms.
