Fats Fats are naturally occuring esters of long E chain carboxylic acids and the triol glycerol(1, 2 3-propanetriol). They are also called glycerides Hydrolysis of fats yields glycerol and three carboxylic acids. The straight chain g carboxylic acids which may be obtained from fats are frequently called fatty acidsOrganic Chemistry Organic Chemistry Xiamen Xiamen University University Fats „ Fats are naturally occuring esters of long chain carboxylic acids and the triol glycerol(1,2,3-propanetriol).
