L-proline (abbreviated as proline) CAS 47-85-3 is one of the twenty amino acids in human protein synthesis. It is a colorless to white crystal or crystalline powder at room temperature, slightly odorous, slightly sweet in taste, easily soluble in water and ethanol, insoluble in ether, butanol, and isopropanol, and soluble in inorganic acids. Amino acids are a general term for a class of organic compounds containing amino and carboxyl groups. The presence of amino acids in the human body not only provides important raw materials for synthesizing proteins, but also provides a material basis for promoting growth, normal metabolism, and maintaining life.
