Lipids are important fats that serve different roles in the human body. A common misconception is that fat is simply fattening. However, fat is probably the reason we are all here.Throughout history, there have been many instances when food was scarce.n fact, phospholipids are synthesized in the body to form cell and organelle membranes. In blood and body fluids, phospholipids form structures in which fat is enclosed and transported throughout the bloodstream. Sterols are the least common type of lipid. Cholesterol is perhaps the best well-known sterol.
What do lipids do for you? You have many different types of lipids in your body including fats, oils, waxes and steroids. Your body uses fats as a supply and store of energy: a gram of fat contains more than double the amount of energy present in a gram of carbohydrate. The steroids in your body include some hormones. Other lipids make up the outer layer of all your cells, and the fatty sheaths that insulate nerve fibres.
