Zuccheri e nucleobasi della spina dorsale

<p>Applications N-Succinyl-5-aminoimidazole-4-carboxamide Ribose 5’-Phosphate is a metabolite of Purine. Since adenosine is a potent inhibitor of neuronal function, depressing the release of several excitatory transmitters and causing direct hyperpolarization of neurons, it was possible that the symptoms seen in adenylosuccinate lyase (ASase) deficient patients could reflect an interference of succinylpurines with neurotransmission.<br>References Gollub, E.G., et al.: J.
