Biological role of lipids. :. Lipids are found naturally in all living organisms.. Cholesterol. Rich in hydrocarbon. Polar group (usually small). Oleic acid. Lipids serve a wide variety of functions. Vitamin K. Surfactants. Protection. Membrane. components. Insulation. Energy storage. They are insoluble in water and highly soluble in one or more of the following solvents: ether, chloroform, benzene and acetone. . Make up about 5% from organic substances which enter in the structure of living cell .. are a diverse group of compounds that are insoluble in water but soluble in organic solvents such as ethanol.. The most common types of lipid are . triglycerides. (sometimes known as true fats or neutral fats), but other important lipids include waxes, steroids and cholesterol.. by. Ms. . P. . . H. . Giri.
