Application:	L-Arginine-Dependent Nitric Oxide Production in the Blood of Patients with Type 2 Diabetes: A Pilot, Five-Year Prospective Study.: This study examines the role of L-Arginine in nitric oxide production in diabetic patients, proposing its potential benefits for managing vascular complications in diabetes (Stoian et al., 2024 ).
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.
