How is Ester bond formed in Fats?

Fats are macronutrients with highest energy storing potential. They are insoluble in water.

Ester bond formation in fats?

Watch this simple 2 minute video

Fats are made up of two types of smaller molecules: glycerol and fatty acids

Glycerol is a 3-C alcohol with a hydroxyl group attached to each carbon

A fatty acid consists of a carboxyl group attached to a long hydrocarbon skeleton

In a fat, 3 fatty acids are joined to 1 glycerol by ester linkage, forming triacylglycerol, or triglyceride

Ester Bond Formation in fats?
Here the OH of the carboxyl group (-COOH) group of each fatty acid bonds with 1st, 2nd and 3rd carbon OH of the glycerol by ester linkage relaesing 3 molecules of water (H2O)
This is how ester bond is formed in fats.
