High-performance liquid chromatography of guanidino
compounds using benzoin as a pre-column fluorescent derivitization reagent.
The first pathway to be discovered for the endogenous production of NO was through the five-electron oxidation of the guanidino
nitrogen group of L-arginine (a semiessential amino acid) by a group of enzymes called nitric oxide synthase (NOS) localized to the vascular endothelium.
A creatina (acido a-metil guanidino
acetico) e uma substancia derivada dos aminoacidos arginina, glicina e metionina sendo sintetizadas nos rins, pancreas e figado, alem disso, a mesma pode ser obtida por meio da alimentacao, principalmente pela ingestao de carne vermelha e peixe, podendo atingir uma producao diaria (aproximadamente 2g/dia) equivalente a taxa de fosforilacao da creatina fosfato (Walker, 1979).
There is significant evidence suggesting that oxygen free radicals play roles in renal ischemia, accumulation of uremic toxins such as urea nitrogen and guanidino
compounds, and depletion of SOD, catalase, GSH-Px, and GSH, which are considered to be natural free radical scavengers (De Vecchi et al.
compounds in guanidinoacetate methyltransferase deficiency, a new inborn error of creatine synthesis.
A sintese de oxido nitrico ocorre principalmente pela oxidacao dos dois nitrogenios guanidino
do aminoacido L-arginina, que e convertida em L-citrulina, e uma reacao catalisada por uma familia de enzimas denominadas oxido nitrico sintase (Dusse e colaboradores, 2003).
Serum creatine, creatinine, and other guanidino
compounds in patients with thyroid dysfunction.
The separation of GAA and Cr+Crn from other guanidino
compounds and interfering arginyl-containing oligopeptides was achieved in 20 min.
compounds in guanidinoacetate methyltransferase defciency, a new inborn error of Creatine synthesis.
Effect of endotoxemia on plasma and tissue levels of nitric oxide metabolites and guanidino
Aptamers have been shown to discriminate closely related molecules from their targets on the basis of small structural changes, such as a methyl group (25, 26), a hydroxyl group (27, 28), and a urea vs a guanidino
