Step 1: Definition of Fats.
Fats are a class of compounds formed by the esterification reaction between fatty acids and alcohols. The alcohol involved in the formation of fats is glycerol. Step 2: Esterification Reaction.
The general reaction for the formation of fat is: In this reaction, glycerol ( ) reacts with fatty acids, resulting in the formation of an ester (fat). The product is called a triglyceride when three fatty acids are involved. Step 3: Conclusion.
Hence, fats are esters formed from glycerol and higher fatty acids.
