Proline

Proline (abbreviated as Pro or P) is an α-amino acid, one of the twenty DNA-encoded amino acids. It is unique among the 20 protein-forming amino acids in that the amine nitrogen is bound to not one but two alkyl groups, thus making it a secondary amine.

Proline is a conditional amino acid. Conditional amino acids are usually not essential, except in times of illness and stress. They include: arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine.

Proline and hyperprolinemia type 2

Hyperprolinemia type 2 results in an excess of a particular protein building block (amino acid), called proline, in the blood. This condition generally occurs when proline is not broken down properly by the body. Hyperprolinemia type 2 causes proline levels in the blood to be 10 to 15 times higher than normal, and it also causes high levels of a related compound called pyrroline-5-carboxylate. Some people with this condition develop mild mental retardation and seizures; however, the symptoms of this disorder vary in severity among affected individuals.
