The video explains that the human body uses 20 amino acids to form proteins. It describes the structure of amino acids, which includes an amino group, a carboxylic acid group, and a side chain attached to a central carbon atom. The video also highlights essential amino acids, which cannot be synthesized by the body and must be obtained through diet.
