| L-Citrulline Usage And Synthesis |
Chemical Properties | White powder | Originator | StaminO2,ErgoPharm | Uses | An amino acid, L-Citrulline can be used in the treatment of asthenia and as an essential intermediate in the biosynthesis of nitric oxide.
| Uses | L-Citrulline, is used as an essential intermediate in the biosynthesis of nitric oxide from L-arginine . It is also used as a nutritional drink and biochemical reagent. | Definition | ChEBI: L-citrulline is the L-enantiomer of citrulline. It has a role as an EC 1.14.13.39 (nitric oxide synthase) inhibitor, a protective agent, a nutraceutical, a micronutrient, a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is an enantiomer of a D-citrulline. It is a tautomer of a L-citrulline zwitterion. | Manufacturing Process | Citrulline is obtained as a result of a reaction of L-arginine hydrochloride with
sodium hydroxide, copper oxide and hydrogen sulfide.
In practice it is usually used as malate salt | Therapeutic Function | Stimulant, Detoxicant | Biochem/physiol Actions | L-Citrulline, when orally administered is found to ameliorate the condition of sickle cell disease in humans. L-citrulline can be a replacement for L-arginine administration in case of defective NO synthetase. L-Citrulline supplementation is found to fulfill the purpose of NO-dependent signaling. | target | NO | IL Receptor | Purification Methods | Likely impurities are arginine and ornithine. Crystallise S-citrulline from water by adding 5 volumes of EtOH. Also crystallise it from water by addition of MeOH.
