Proline

Other names: Pyrrolidine-2-carboxylic acid, L-proline

The amino acid Proline, which is also known as Pyrrolidine-2-carboxylic acid or L-proline, is unique and differs greatly in its structure from other amino acids. It has a peculiar cyclic structure consisting of three methylene groups (-CH2-) and a five-membered ring formed by an amino group (-NH2). This structure allows it to form special peptide bonds that affect the shape and function of the proteins into which it is incorporated. Proline is essential for the formation of collagen, a protein that provides strength and flexibility to tissues such as skin, tendons, bone and cartilage.

Proline is used in many products. It is included in drinks designed for athletes because it helps regenerate muscle tissue. It is also found in cosmetic products where it helps hydrate the skin and has anti-aging properties. This amino acid is also an ingredient in some medicines, where its abilities to increase the elasticity of blood vessels and promote collagen formation are exploited. Proline is also used in the food industry, where it helps stabilize and improve the texture of foods during processing.
