Created page with 'Proline is an imino acid not an amino acid.' |
Added the references correctly, that is, I added them as explained in the lecture. Cleaned up the text. Removed some stray code. |

Imino acids are a group of compounds that contain both an amide and a carboxyl group, bonded to the alpha carbon molecule[1]. The difference between amino acids and imino acids is in the bonding of the nitrogen in the amide group. In imino acids, the nitrogen forms a double covalent bond to another molecule, or two single bonds to two different 'R' groups.
Proline
Although Proline is often referred to as an amino acid, it has a secondary amide group, making it an imino acid[2]. This is due to its cyclic nature, as the nitrogen in the amide group is bonded to two different 'R' groups in the ring.
