Proline
Proline is an imino acid. It has a molecular weight of 115.13 and its molecular formula is C5H9NO2. It is also classified as a hydrophobic amino acid.
Proline has an aliphatic side chain, which is bonded to the nitrogen atom and the alpha-carbon atom. It influences protein architecture, because it's structure makes it more conformationally restricted than other amino acids [1].
