Neutral fat

EN Texte en anglais Pas encore d'article dans ta langue : extrait en anglais.

Neutral fats, also known as true fats, are simple lipids formed by the dehydration synthesis of one or more fatty acids with an alcohol such as glycerol. Neutral fats are commonly referred to as triglycerides. These lipids are hydrophobic and dense due to their long hydrocarbon chains, and their main biological function is energy storage as body fat. Neutral fats can be tightly packed due to the structure of their fatty acid chains. While triglycerides are primarily used for energy storage, they may also contribute to lipid membranes, where they help provide flexibility. Additionally, they can serve as precursors or components of signalling molecules. A wide variety of neutral fats exist, owing to the diversity of fatty acids that can be incorporated and the multiple bonding arrangements possible with glycerol. An example is a monoglyceride, which has one fatty acid combined with glycerol, a diglyceride, which has two fatty acids combined with glycerol, or a triglyceride, which has three fatty acids combined with glycerol.
