Product Description:
Arginine, nrog rau cov tshuaj formula C6H14N4O2 thiab molecular hnyav ntawm 174.20, yog ib tug amino acid compound. Koom nrog hauv lub voj voog ornithine hauv tib neeg lub cev, txhawb kev tsim cov urea, thiab hloov cov ammonia tsim hauv tib neeg lub cev mus rau hauv cov tshuaj tsis muaj tshuaj lom los ntawm lub voj voog ornithine, uas tau tawm hauv cov zis, yog li txo cov ntshav ammonia concentration.
Muaj ntau dua concentration ntawm hydrogen ions, uas yuav pab kho cov acid-base tshuav nyiaj li cas nyob rau hauv hepatic encephalopathy. Ua ke nrog histidine thiab lysine, nws yog ib qho yooj yim amino acid.
Kev ua tau zoo ntawm L-Arginine 99%:
Rau kev tshawb fawb biochemical, txhua yam ntawm hepatic coma thiab txawv txav hepatic alanine aminotransferase.
Raws li cov khoom noj khoom haus thiab tshuaj tsw qab. Cov tshuaj tsw qab tshwj xeeb tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv cua sov nrog cov suab thaj (amino-carbonyl cov tshuaj tiv thaiv). GB 2760-2001 qhia cov txuj lom zaub mov tso cai.
Arginine yog ib qho tseem ceeb amino acid los tswj kev loj hlob thiab kev loj hlob ntawm cov me nyuam mos thiab cov me nyuam yaus. Nws yog ib qho nruab nrab metabolite ntawm lub voj voog ornithine, uas tuaj yeem txhawb kev hloov pauv ntawm ammonia rau hauv urea, yog li txo cov ntshav ammonia.
Nws kuj yog ib feem tseem ceeb ntawm cov phev protein, uas yuav txhawb nqa phev ntau lawm thiab muab phev zog zog. Tsis tas li ntawd, arginine intravenous tuaj yeem ua rau lub pituitary tso tawm cov tshuaj hormones loj hlob, uas tuaj yeem siv rau kev kuaj pituitary.
