L-Proline CAS 147-85-3

L-Proline is one of the 18 amino acids that the human body uses to synthesize proteins. It is a colorless to white crystal or crystalline powder at room temperature, with a slight odor and a slightly sweet taste. It is very soluble in water, difficult to dissolve in ethanol, and insoluble in ether and n-butanol. 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 an important raw material for synthesizing proteins, but also provides a material basis for promoting growth, conducting normal metabolism, and maintaining life.
