Lipids are fatty wax-like biomolecules which are found in the body. They are insoluble in water and soluble in organic solvents. They keep the body going, store energy, sends signals throughout the body, and communicate with cell membranes. There are a plethora of lipids found in the body. Some of these include wax, steroids, glycerides, phospholipids, fats, and fat-soluble vitamins. Phospholipids and cholesterol act as cell membrane components. Fats are among the numerous lipid subclasses in the body.
Fat is a naturally oily substance that can be found in human and animal bodies, usually when accumulated as a layer under the skin or near specific organs. Some examples of fats include phospholipids, cholesterol, and triglycerides. Fats could also be classified as saturated fat, unsaturated fat, solid fats, and liquid fats. Fat is stored in individual cells in the body called adipocytes.
