FUNCTION Energy Fat supplies energy Yields 9 kcals/g Has a high energy density, it is a very concentrated source of calories Energy density - the amount of energy contained in a given weight or volume of  a food. A food with high energy density contains a large amount of energy in a  small amount of food. Storage Form of Energy We use fat for storage because of its energy density Ounce for ounce, fat as over twice the calories We store triglyceride in adipose tissue The composition of this fatty tissue reflects the diet Cell Membranes Consist mostly of phospholipids arranged in the lipid bilayer Double layer of phospholipids   with hydrophobic fatty acid tails oriented inward,  and the hydrophilic glycerol and phosphate heads oriented to the watery outside Proteins embedded in the bilayer act as receptors, carriers, and in various other  functions
