Group of organic molecules (c, o, h) Oils: lipids that are liquid at room temperature. Fats: lipids that are solid at room temperature. Like carbohydrates, fat given a bad reputation.

Insulate the body (keep up warm in cold temperatures) Make up oils that lubricate body surfaces. Cholesterol forms myelin insulin coating around nerves. Cholesterol and phospholipids form the structure of the cell membrane. Cholesterol and fatty acids used to make regulatory molecules in the body. Cholesterol makes steroid hormones (estrogen, testosterone) and stress hormones (cortisol) Eicosanoids made from essential fatty acids help regulate blood pressure, blood clotting, sleep/wake cycles, body temperature, inflammation, stomach secretions and immune and allergic responses. Essential fatty acids important for growth, development, fertility and maintaining the structure of red blood cells and cells in the skin and nervous system.
