lornithine

L-Ornithine ((S)-2, 5-diaminopentanoic acid) is a non-protein amino acid. L-Ornithine is mainly used in the urea cycle to remove excess nitrogen from the body. L-Ornithine is renoprotective. L-Ornithine has antifatigue effects.

N(delta)-acetylornithine is a non-protein amino acid and a defence-related plant metabolite, primarily found in Arabidopsis. The inclusion of N(delta)-acetylornithine in feed can reduce the reproduction of Myzus persicae and exhibits certain toxic properties.

gamma-Glutamylornithine can be isolated from the urine of patients with hyperornithinemia.

N-Acetylornithine (N-Acetyl-L-ornithine) is a minor component of deproteinized blood plasma of human blood. Human blood plasma contains a variable amount of acetylornithine, averaging 1.1 +/- 0.4 μmol/L. Urine contains a very small amount of acetylornithine, approximately 1 nmol/mg creatinine (1 μmol/day).

L-Ornithine hydrochloride ((S)-2,5-Diaminopentanoic acid) has an antifatigue effect by increasing the efficiency of energy consumption and promoting the excretion of ammonia. It is one of the key reactants in the urea cycle.
