Siv Arginine yog ib qho tseem ceeb amino acid rau 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 txhawb kev hloov pauv ntawm ammonia rau urea, yog li txo cov ntshav ammonia. Nws kuj yog ib feem tseem ceeb ntawm cov phev protein, uas txhawb nqa cov phev ntau lawm thiab muab lub zog rau cov phev txav. Tsis tas li ntawd, arginine intravenous, tuaj yeem txhawb kev loj hlob hormone tso tawm, tuaj yeem siv rau kev kuaj pituitary.
