Biosynthesis
The biosynthesis of malvalic acid starts when the electrophilic addition of methylene occurs via SAM the alkylating agent. That electrophilic addition gives a raise to carbocation intermediate. At this point, the cation discharged by formation of cyclopropane ring and loss of proton. The Enzyme cyclopropane fatty acid synthesis catalyzed the reaction to form dihydrosterculic acid, which will be dehydrogenated to sterculic acid. Finally, sterculic acid will go over chain shortening by α-Oxidation in which carboxyl carbon would be removed to form malvalic acid.
