| | L-Ornithine Usage And Synthesis |
| Chemical Properties | It is a white solid, but as it does not crystallise readily, it is usually found in a paste-like form. It is readily soluble in water and ethanol, sparingly soluble in diethyl ether, and its solution is alkaline. | | Occurrence | Ornithine is found in many foods, including fish, dairy products and pulses. Sardines, salmon and herring are particularly good sources. | | Uses | hepatoprotectant, anticholesteremic | | Definition | ChEBI: L-ornithine is an optically active form of ornithine having L-configuration. It has a role as a hepatoprotective agent, a mouse metabolite and an algal metabolite. It is an ornithine and a non-proteinogenic L-alpha-amino acid. It is a conjugate base of a L-ornithinium(1+). It is a conjugate acid of a L-ornithinate. It is an enantiomer of a D-ornithine. | | Synthesis Reference(s) | Canadian Journal of Chemistry, 31, p. 1060, 1953 DOI: 10.1139/v53-139 | | Safety Profile | Mutation data reported. When heated to decomposition it emits toxic vapors of NOx. | | Purification Methods | Crystallise L-ornithine from water containing 1mM EDTA (to remove metal ions).
