|Section2= |Section3= }} Malvalic acid is a cyclopropenic fatty acid found in cottonseed oil. The cyclopropene ring is thought to be one of the causes of abnormalities that develop in animals that ingest cottonseed oil. This reactivity could be cause for concern depending on concentration. Hydrogenation of the oil destroys malvalic acid. ==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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Malvalic acid」の詳細全文を読む スポンサード リンク
