D-Leucine Use and Manufacturing

Methods of Manufacturing

Using acetyl-DL-leucine as the raw material, the L-leucine is removed by the acylase treatment, and then hydrolyzed in hydrochloric acid to obtain the crude product, and the pure product is obtained after crystallization and purification.

Uses

Used for biochemical research.
