Proline P (Pro)
Chemical Properties: Cyclic (Biosynthesis of Proline)
Physical Properties: Nonpolar

Proline shares many properties with the aliphatic group.

Proline is formally NOT an amino acid, but an imino acid. Nonetheless, it is called an amino acid. The primary amine on the α carbon of glutamate semialdehyde forms a Schiff base with the aldehyde which is then reduced, yielding proline.

When proline is in a peptide bond, it does not have a hydrogen on the α amino group, so it cannot donate a hydrogen bond to stabilize an α helix or a α sheet. It is often said, inaccurately, that proline cannot exist in an α helix. When proline is found in an α helix, the helix will have a slight bend due to the lack of the hydrogen bond. Proline is often found at the end of α helix or in turns or loops. Unlike other amino acids which exist almost exclusively in the trans- form in polypeptides, proline can exist in the cis-configuration in peptides. The cis and trans forms are nearly isoenergetic. The cis/trans isomerization can play an important role in the folding of proteins and will be discussed more in that context.

Proline is the only cyclic amino acid.

Biosynthesis of Proline
Glutamic acid is easily converted into proline. First, the γ carboxyl group is reduced to the aldehyde, yielding glutamate semialdehyde. The aldehyde then reacts with the α-amino group, eliminating water as it forms the Schiff base. In a second reduction step, the Schiff base is reduced, yielding proline.

Proline was first isolated from casein in 1901, and unlike any of the other amino acids it is readily soluble in alcohol. It is a nonessential amino acid and can be synthesized from glutamic acid and does not require dietary sources. As information is very limited on this nutrient, our page is also very short.

Proline is required for

Proline improves skin texture and aids collagen formation and helps contain the loss of collagen during aging. Collagen in the skin contains hydroxyproline and hydroxylysine, which is formed from proline and lysine, in which ascorbic acid seems to be important in this conversion. Collagen contains about 15 % proline. It is also thought to be important in the maintenance of muscles, joints and tendons.

Proline is best used with
According to the current information available it would be recommended that an ample supply of vitamin C (ascorbic acid) be present to maximize the efficiency of proline.

Food sources
Proline is mostly found in meat sources
  • Functioning as a precursor to hydroxyproline
  • Production of collagen, cartilage and connective tissue
  • Joint and tendon health
  • Tissue repair and wound healing
  • Maintenance of healthy skin and prevention of aging in skin tissue
  • Supporting DNA synthesis
