Ester linkages in Lipids
Ester linkages are covalent bonds that occur between a carboxylic acid group and an alcohol group. These linkages are commonly found in lipids, which are a diverse group of biomolecules that are insoluble in water and soluble in nonpolar solvents.
Lipids are composed of a glycerol molecule that is esterified with three fatty acids. The ester linkages between the carboxylic acid groups of the fatty acids and the hydroxyl groups of the glycerol molecule form the backbone of the lipid molecule. The ester linkages are formed through a condensation reaction, where a molecule of water is eliminated.
Ester linkages are also present in other types of lipids, such as phospholipids, which are a major component of cell membranes. In phospholipids, the ester linkages are formed between the hydroxyl group of glycerol and the phosphate group, and between the phosphate group and the hydroxyl group of a polar head group.
In summary, ester linkages are commonly found in lipids, where they form the backbone of the molecule. These linkages play an important role in the structure and function of lipids, including their solubility, fluidity, and stability.

Lipids are actually triglycerides .a triglyceride consist of glycerol and fatty acids which are held together by Ester linkages in condensation reaction releasing three water molecules.
