DETAILS

Description (English)

Biochem/physiol Actions
Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
Other Notes
Exhibits stabilizing effects on plant protoplasts1; pH drift correction in IEF of proteins2; Growth requirement of various microorganisms3.
