- describe the four major in terms of there structure and function. There are four main classes of biologically important organic compounds lipids, carbohydrates, Nucleic acid, and proteins. All four groups have distinctive properties and they are all important to living organisms. The first of the four main organic compounds are lipids. Lipids are distinguished from the other classes of organic compounds because they don’t dissolve in water but are soluble in other organic solvents. Lipids are made up of mostly carbon, hydrogen, oxygen, and phosphorus. The most important lipids are phospholipids, which are used in the cell membrane. Fats and oils, also known as triglycerides, serve as stored energy reserves in plant and animal cells. These can be broken down to release energy when the organism needs it. Other lipids are the waxes, which form coatings on the leaves of plants and the skins of animals, and steroids, which include vitamin D and several hormones.
