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 triglycerideHere 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)
