Document Summary
Major form of lipid in the body and in food. Composed of 3 fatty acids and a glycerol. Alpha end acid group (double bond o, 1 c, 1oh) Chain of carbons have no double bonds, so it is saturated. One double bond in the chain of carbons (liquids at room temp) At least two double bonds (or more) (liquid at room temp) Body can only make double bonds after the 9th carbon from the omega end. Needed for immune function, vision, cell membrane, and production of hormone-life compounds. Omega end 1st double bond is on the 6th carbon from the omega end. Omega-3 (linolenic acid) eicosapentaenoic acid (epa), docosahexaenoic acid (dha) Omega end 1st double bond is located on the 3rd carbon from the omega end. Has at least one fatty acid replaced with phosphorus compound. Found in the body, especially in the brain, as parts of cell membranes (structural)
