L-proline (referred to as proline) is one of the 20 kinds of amino acids that the human body synthesizes protein. It is colorless to white crystal or crystalline powder at room temperature. It has a slight odor and a slightly sweet taste. It is easily soluble in water. Amino acid is 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 protein synthesis, but also provides a material basis for promoting growth, normal metabolism, and maintaining life.
