RCO R' + H0-R" - R-C-0-R" + R'OH Ester Alcohol New ester New alcohol Fats and oils are esters, derived from glycerol [HOCH₂CH(OH)CH₂OH] and high-molar-mass organic acids with at least 12 carbon atoms in the chain. Common fatty acids found in fats and oils are lauric acid myristic acid palmitic acid stearic acid oleic acid CH3(CH2) 10CO₂H CH3(CH₂) 12CO₂H CH₂(CH₂)14CO₂H CH3(CH2) 16CO₂H CH3(CH₂)7CH=CH(CH₂)7CO₂H
