Chemische Eigenschaften
White powder; mild green bark aroma.
Chemische Eigenschaften
L(+)-Ornithine hydrochloride is white crystalline powder
Verwenden
L(+)-Ornithine hydrochloride is a nonprotein amino acid used in the biosynthesis of L-arginine, L-proline and polyamines.
Verwenden
L(+)-Ornithine hydrochloride is a non-essential amino acid for human development but is required intermediate in arginine biosynthesis. L(+)-Ornithine hydrochloride is found in virtually all vertebrate tissues as well as incorporated into proteins, such as tyrocidine. Isolation from chicken excreta.
Verwenden
Non-essential amino acid for human development but is required intermediate in arginine biosynthesis. Found in virtually all vertebrate tissues as well as incorporated into proteins, such as tyrocidine. Isolation from chicken excreta.
Aroma threshold values
Low strength odor, green type.
Taste threshold values
Very mild sweet taste at 500.00 ppm in water.
Allgemeine Beschreibung
L-Ornithine is the functional metabolite of L-arginine.
Flammability and Explosibility
Not classified
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.
Sicherheitsprofil
Mildly toxic by ingestion. When heated to decomposition it emits very toxic fumes of NOx and HCl.
läuterung methode
Likely impurities are citrulline, arginine and D-ornithine. Crystallise the monohydrochloride from water by adding 4volumes of EtOH and dry it in a vacuum desiccator over fused CaCl2. [Rivard Biochemical Preparations 3 98 1955.] The dihydrochloride [6211-16-1] has m 202-203o and [ ] D +18.4o (c 2.3, 6N HCl) after recrystallisation from MeOH/Et2O [Zaoral & Rudinger Collect Czech Chem Commun 24 2009 1959].
