| L-proline (abbreviated as proline) 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 iso-propanol, 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. |
