Simple esters are made from an organic acid and an alcohol.
ester functional group is of primary importance in the biochemical
group of compounds called waxes, triglycerides, and phospholipids.
The simplified reaction reveals the process of breaking some
bonds and forming the ester and the by product, water. Refer
to the graphic on the left for the synthesis of carnuba wax.
First, the -OH (red) bond on the acid is broken and the -H (red)
bond on the alcohol is also broken. Both join to make HOH, a
Secondly, the oxygen of the alcohol forms a bond (green) to
the acid at the carbon with the double bond oxygen. This forms
the ester functional group.
The long carbon chains do not participate in the reaction,
but are just part of the final molecule.
