What Are Proteins | Cells | Biology | FuseSchool

In this video, we are going to discuss the structure and uses of protein molecules.

Proteins are long-chain molecules made of strings of amino acids joined together. All amino acids are compounds with a similar basic structure: they have an amino group, a carboxyl group, and a side chain, or R group, that is specific to each amino acid.

There are 20 different amino acids.
