Sapienic acid (16:1, n-10, cis-6 hexadecenoic, or sapienate) is a fatty acid that is a major component of human sebum. Sapienic acid is a sebum fatty acid that is unique to humans (from whose scientific name it takes the root sapiens). The equivalent fatty acid in mouse sebum is palmitoleic acid.[1] Sapienic acid has been implicated in the development of acne,[2] and it may have potent antibacterial activity.[3]
Delta-6-desaturation of palmitic acid leads to the biosynthesis of sapienic acid. In other tissues linoleic acid is the target for delta 6 desaturase, but linoleic acid is degraded in sebaceous cells, allowing the enzyme to desaturate palmitic to sapienic acid.[4][5] A two-carbon extension product of sapienic acid, sebaleic acid, is also present in sebum.
