Almost all vegetable oils contain triglycerides of different saturated fatty acids C12:0–C20:0 (lauric, myristic, palmitic, stearic, arachic acids), monounsaturated fatty acids C16:1–C20:1 (palmitoleic, oleic, eicosenoic acids), polyunsaturated fatty acids C18:2 and C18:3 (linoleic, linolenic acids) (Table 1).
