L-Norvaline enhances NO production from activated macrophages. It is known to promote tissue regeneration and muscle growth and become a precursor in the penicillin biosynthetic pathway. It also can be used for nutrition agent and drug synthesis. For example: it can react with phthalic acid anhydride to get N,N-phthaloyl-L-norvaline.
