What is L-Hydroxyproline?

H&Z® L-hydroxyproline is a common nonstandard protein amino acid, white flake crystal or crystalline powder.It is easily soluble in water and slightly soluble in ethanol. It has a unique sweet taste in bitterness and can improve the flavor and quality of juice drinks and cool drinks. It has special flavor and can be used as fragrant material.
