What are lipids?

Lipids are organic compounds composed mainly of carbon, hydrogen, and oxygen, but they also may contain other elements, such as phosphorus and nitrogen. Lipids usually have more than twice as many hydrogen atoms as oxygen atoms. They are insoluble in water, but can be dissolved in certain organic solvents such as ether, alcohol, and chloroform. Lipids include fats, oils, phospholipids, steroids, and prostaglandins.
