|Section2= |Section3= }} Nervonic acid (24:1, n-9) is a fatty acid. It is a monounsaturated analog of lignoceric acid (24:0). It is also known as selacholeic acid and cis-15-tetracosenoic acid. It exists in nature as an elongation product of oleic acid (18:1 Δ9), its immediate precursor being erucic acid. Nervonic acid is particularly abundant in the white matter of animal brains and in peripheral nervous tissue where nervonyl sphingolipids are enriched in the myelin sheath of nerve fibers. In the same way, recent studies have concluded that nervonic acid is implicated as an intermediate in the biosynthesis of nerve cell myelin. This acid is an important member of the group of the cerebrosides, which are fatty acids of the glycosphingolipids group, important components of the muscles and the central nervous system and peripheral. Indeed, it is one of the major fatty acids in brain sphingolipids, normally accounting for approximately 40% of the total fatty acids in sphingolipids. == Structure == As it is defined as a monounsaturated fatty acid, it has one double bond in the fatty acid chain and all the remaining carbon atoms are single-bonded. It is classified in the sub-group of very long chain fatty acids (VLCFA), which includes molecules containing more than 20 carbon atoms. It has specifically 24-carbon backbone and the sole C=C double bond originating from the methyl end is in n-9 or omega-9 (ω-9).〔 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「Nervonic acid」の詳細全文を読む スポンサード リンク
