Description

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 protoplasts; pH drift correction in IEF of proteins; Growth requirement of various microorganisms.
