Natures way of condensing energy stores also insulates/protects organisms. Glycerol + 2 fatty acids + phosphorus. Phosphorus part makes it soluble in water. Fatty acids make it soluble in fat. Large molecules of interconnected rings of carbon (c) atoms with side chains of c, hydrogen, and oxygen atoms attached. Cholesterol: is found in an animal cell membranes, is nonessential, forms plaques that cause atherosclerosis. Cholesterol serves as the raw material for: bile, vitamin d, steroid hormones including sex hormones. Made up of glycerol backbone and 3 fatty acids. Fatty acids classified by length, number of carbon atoms, and location of double bonds, organization of hydrogen around the double bonds. A fatty acid carrying the maximum umber of hydrogen atoms. A fatty acids with less than maximum hydrogen atoms. Arise when polyunsaturated oils are hydrogenated: advantage: control consistency and oxidation of fats, disadvantage: increase ldl (low density lipoproteins. Essential for normal infant growth and development.
