D-ornithine - Introduction
D-ornithine is an amino acid that is the D-isomer of ornithine. D-ornithine has the following properties: colorless crystals, soluble in water, slightly soluble in alcohol. It is stable under acidic conditions but easily degrades under alkaline conditions.
D-ornithine have important uses in biology. It is one of the key raw materials for the synthesis of polypeptide antibiotic streptomycin. In addition, D-ornithine can also be used for the synthesis of other drugs, peptide hormones and nutritional supplements. In the food industry, D-ornithine are used as additives to enhance the umami taste of foods and to increase their flavor characteristics.
One method of making D-ornithine is through the chemical synthesis of ornithine. The commonly used method is to split L-ornithine by enzymatic or chemical means to extract D-ornithine.
Regarding the safety information of D-ornithine, it belongs to non-toxic substances and has no specific toxicity and irritation. But as a chemical, it still needs to be handled and used properly. During use, it is necessary to avoid contact with strong oxidants, strong acids, strong bases and other substances to avoid danger. In addition, it should be handled in strict accordance with safe procedures to avoid inhalation, ingestion or contact with eyes and skin. In case of accidental contact, rinse immediately with plenty of water and seek medical help.
