Pidolic acid is an organic compound often referred to as proline, an amino acid that plays a crucial role in various biological processes. Synonymous with proline, pidolic acid is a vital component for protein synthesis, collagen formation, and the proper functioning of the immune system. This nonessential amino acid is commonly found in foods like meat, dairy products, and soybeans. Pidolic acid, or proline, is also used in the production of dietary supplements and pharmaceuticals due to its potential health benefits. Furthermore, proline is recognized for its antioxidant properties, aiding in the protection and repair of cells from oxidative stress.
