Step by step solution

01

Esterification

Esterification is a chemical reaction in which two reactants (often an organic acid (RCOOH) and an alcohol (ROH) combine to form an ester (RCOOR) and H₂O. Hydrolysis is the reversible reaction.

02

Esterification of palmitate

Palmitate (fatty acid) is esterified with ${CH}_{3} {{(CH}_{2})}_{5} {CH(CH}_{2})_{10} {COO}^{-}$ to produce an ester (hydroxy stearate) in the following reaction:

Hence, palmitate fatty acids were used to build the molecule which functions as a signaling molecule
