Hello, there!
There are 4 bio-molecules.
1. Carbohydrates. They provide the body quick energy
2. Lipids. They provide long term energy storage.
3.Proteins. They help to repair/build tissues for your body.
4. Nucleic acid. It holds the genetic information/code for your body.
I hope I helped and that you are having a wonderful school year so far!
Let me know if you need anything else!
