| polysaccharide | a carbohydrate (e.g. starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together. |
| 4 main biomolecules and what the body uses them for | carb-It helps with the cell walls and is a big part of ATP, which gives us energy. protiens-helps with muscle tissue, and receptors and enzymes are made out of proteins. lipids-Used to make up the cell membrane structure. nuelic acids-contains genti |

| Macromolecules | Big molecules (made of hundreds or thousands of atoms). They are only found in living things, and examples of them include proteins, DNA, fats, and carbohydrates. |
| monomer | It is a small molecule that can be joined with other monomers to form a polymer |
| polymer | A large, carbon-based molecule formed by monomers |
| Hydrolysis | water is added back to break the bonds. This breaks down polymers |
| dehydration synthesis | water is removed to join monomers. used to build polymers (many smaller molecules joined together) |
| Why is carbon a good backbone for most biomolecules | it can form 4 covalent bonds |
