Definition
ChEBI: 12-hydroxyoctadecanoic acid is a hydroxy fatty acid that is stearic acid bearing a hydroxy substituent at position 12. It has a role as a plant metabolite and a bacterial xenobiotic metabolite. It is a hydroxyoctadecanoic acid and a secondary alcohol. It is a conjugate acid of a 12-hydroxyoctadecanoate.
Synthesis
Castor oil is hydrogenated at 5MPa and 185°C in the presence of nickel-aluminum catalyst. The reaction product is obtained by saponification and acid hydrolysis to obtain DL-12-Hydroxystearic acid.
