Study Notes
Amino Acids and Proteins
- 20 amino acids are coded by DNA to appear in proteins
- The properties of proteins are determined by their unique sequence of amino acids
- The net charge of an amino acid in its dipolar (zwitterion) form is zero, as it has both a positive and a negative charge
- In an amino acid, all the substituents are attached to the central alpha carbon atom
- The basic structural units of proteins are amino acids
