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

Proline-rich antimicrobial peptides (PrAMPs) from insects and mammals have recently been evaluated for their pharmaceutical potential in treating systemic bacterial infections. Besides the native peptides, several shortened, modified, or even artificial sequences were highly effective in different murine infection models.
