Monounsaturated if one bond is unsaturated (mufa"s) Polyunsaturated if two or more bonds unsaturated ( pufa"s) Food sources are sunflower, corn , and soybean oils. Linolenic acid (ala) , eicosapentanoic acid (epa) and docosahexanoic acid(dha) are the primary members. Required for: a structural component of all cell membranes found in high amounts in the brain and eyes cardiovascular health.
