Answer:
Fat
Explanation:
A fat molecule is an ester made from esterification reaction between glycerol & fatty acid.
Fatty acids have a long aliphatic chain and a terminal carboxylic acid (-COOH) group while a glycerol molecule is a 3 carbon compound with each carbon being attached to a hydroxyl (-OH) group. When carboxylic acid (-COOH) group of fatty acid reacts with hydroxyl (-OH) group of glycerol an ester is produced which is known as triglyceride and some residual water is also released in the reaction. To be more specific, in esterification reaction, - OH of hydroxyl (-OH) group of glycerol and -H of carboxylic acid (-COOH) group of fatty acid react to form ester bond between the two & release water.
Fat is a type of triglyceride. There are two types of triglycerides (1) Fats & (2) Oils.
