L-proline

The biological functions of L-proline
Protein structure maintenance: L-proline is one of the 20 common amino acids that make up proteins. Its cyclic structure can affect the secondary structure of proteins, causing a turn in the direction of polypeptide chains and playing a key role in the structural formation and stability of proteins such as collagen. Collagen contains a large amount of proline and hydroxyproline, which are crucial for maintaining the triple helix structure and stability of collagen.
Participation in biological metabolism: In organisms, proline is involved in multiple metabolic pathways. It can serve as an energy source and provide energy for cells through a series of metabolic reactions. In addition, proline is also involved in processes such as nitrogen metabolism and osmotic pressure regulation.
