General description

L-Ornithine is the functional metabolite of L-arginine.
L-Ornithine is an amino acid that is not coded for by the genetic code. It is formed during the decomposition of argininine by arginase and participates in the urea cycle. Ornithine is the starting point for the formation of a family of polyamines that include spermine, spermidine and putrescine.

Application

L-Ornithine monohydrochloride has been used:
  • as a supplement in Dulbecco′s modified eagle medium (DMEM) for cell growth assays
  • as a component in the standard medium for primary human hepatocytes (PHH) culture
  • as a creatine synthesis inhibitor

Biochem/physiol Actions

L-ornithine acts as a precursor for polyamines. It may modulate the intake of food as an acute satiety signal in the neonatal chick brain.
L-Ornithine is used as a media supplement to support the biosynthesis of polyamines.

The polyamines and their derivatives are essential for life in eukaryotic and most prokaryotic cells, but their exact role in preserving cell function is not clear. These polyamines provide endogenous cations and thus participate in regulation of the intracellular pH;
