Application

L-Ornithine monohydrochloride has been used to study the blocking effect of L-ornithine on the transport system that carries L-arginine for the overproduction of nitric oxide during lipopolysaccharide induced endotoxemia in rat model. It has also been used in decarboxylation test of amino acids.

Biochem/physiol Actions

L-Ornithine is a product of arginase degradation and plays an important role in ammonia metabolism via the urea cycle. In mammals, ornithine serves as a precursor for polyamines and proline biosynthesis. Spermine synthesized from ornithine, is an abundant polyamine observed in tumors such as breast carcinomas. Administration of L-ornithine is known to improve subjective index of sleep quality. L-ornithine reduces the cortisol/DHEA-S (dehydroepiandrosterone) ratio, that is associated with stress. In mice, L-ornithine is found to affect the levels of plasma growth hormone, corticosterone and melatonin levels in mice.

Combined administration of ornithine and phenylacetate (OP) is proposed as a novel treatment of hyperammonemia and hepatic encephalopathy. Ornithine is believed to increase ammonia fixation into glutamine in muscle tissue and glutamine is subsequently thought to react with phenylacetate forming
