Notes: Oleic acid methyl ester is an esterified version of the free acid which is less water soluble but more amenable for the formulation of oleate-containing diets and dietary supplements. Oleic acid (Item No. 90260) is a monounsaturated fatty acid and is one of the major components of membrane phospholipids. Oleic acid contributes about 17% of the total fatty acids esterified to phosphatidylcholine, the major phospholipid class in porcine platelets.{3964}
