1. L-Ornithine L-Aspartate (L-Orn-L-Asp) (CAS: 3230-94-2) was developed in Germany in the 1960s and was the first clinically used for the treatment of alcoholism and hepatic encephalopathy. With the accumulation of clinical application experience, Ornithine Aspartate has been more widely used in the treatment of liver diseases, and has achieved definite curative effects on hepatic encephalopathy, drug-induced liver damage, fatty liver, chronic hepatitis and other diseases. , Has been widely recognized by clinicians. Ornithine aspartate is a stable dipeptide compound prepared by chemical synthesis of L-ornithine and L-aspartic acid, which is extremely soluble in water and almost insoluble in methanol or ethanol. When this product enters the human body, it is decomposed into aspartic acid and ornithine, which can directly participate in liver cell metabolism, and can activate two key enzymes in the liver's detoxification function, thereby helping to remove harmful free radicals and enhance The liver's detoxification function quickly reduces excessive blood ammonia and promotes the repair and regeneration of liver cells, thereby effectively improving liver function and restoring the body's energy balance.
2. L-Ornithine L-Aspartate promotes the speed of cell metabolism in the whole body, accelerates blood circulation, can eliminate toxins and wastes deposited in the body, can promote the metabolism of liver cells, and can also meet the needs of liver cell growth and development energy.
3. L-Ornithine L-Aspartate strengthens the function of liver cells by accelerating the cycle of ornithine, can quickly reduce excessive blood ammonia within a few hours, correct the decompensation of amino acids, and improve the brain Symptoms.
4. L-Ornithine L-Aspartate can increase the energy synthesis of hepatocytes,Aspartate can participate in the synthesis of nucleic acid in hepatocytes, which is beneficial to repair damaged hepatocytes.
5, Most amino acids are used as building blocks to make protein. But L-ornithine-L-aspartate is not used to make protein. Instead it is broken down in the body to provide ornithine and aspartic acid.
6. Recovery in the treatment of liver cirrhosis, diseases, and enhance physical fitness.Pharmaceutical intermediates, biochemical research, compound amino acid combination formula, raw materials for peptide synthesis.Culture, enhance human immunity, resistance to fatigue, beneficial to human body health.
