Biochem/physiol Actions

L-Ornithine is a not encoded by DNA. It is a free amino acid but do not participate in the protein synthesis. It is formed by the action of the enzyme arginase on L-arginine in the process of forming urea. It is implicated in the reduction of blood ammonia level and improves the efficiency of energy production to cause ammonia detoxification. L-ornithine promotes the release of growth hormone by triggering the pituitary gland.

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
