LIPIDS: Triglycerides provide energy during aerobic metabolism, they are stored in the adipose (fat) tissues beneath the skin, within skeletal muscles and around the organs. Cholesterol provides structure for steroid hormones, such as estrogen and androgen, cell membranes, and bile acids. Within cells, lipids regulate fluid balance between the cell and its external fluid environment. Fats in the body cushion organs from shock and blunt trauma and stores energy for future use. Triglycerides are an efficient form of energy storage that can be mobilized when fuel is needed, a small amount of lipids can store a large amount of energy. Lipids are long term energy storage unlike carbs which are for short term usage, Lipid hormones, like steroids and eicosanoids, mediate communication between cells. The fat-soluble vitamins A, D, E, and K are required for metabolism, usually as coenzymes. Fats can either be Saturated or Unsaturated.
