Full Answer

The carbohydrate group contains sugars, such as sucrose, and starches, such as cellulose. Sugars provide energy to living cells, while starches provide structure. The lipids group contains fats and oils, such as phospolipids and triglycerides. They provide energy and insulation and can act as signaling molecules. Proteins are large polymers that have many functions in living things, such as communication between cells, cell movement, structure and chemistry. Nucleic acids contain information needed by the cell. Deoxyribonucleic acid (DNA) carries the genetic code that creates living things. Ribonucleic acid (RNA) codes the DNA into proteins.
