What is Oleic acid?
Oleic acid is an octadec-9-enoic acid in which the double bond at C-9 has Z (cis) stereochemistry. It has a role as an antioxidant, a solvent, a mouse metabolite, a plant metabolite, an Escherichia coli metabolite, an EC 3.1.1.1 (carboxylesterase) inhibitor and a Daphnia galeata metabolite. It is a conjugate acid of an oleate. It derives from a hydride of a cis-octadec-9-ene.
