Puas gallic acid puas tsim kev puas tsuaj rau tib neeg?
Nyob rau hauv kev tshawb fawb txog qhov ncauj mob toxicity, ntawm 5000 mg/kg p.o. Tsis pom cov cim ntawm kev tuag toxicity. Thiab nyob rau hauv ib txoj kev tshawb nrhiav toxicity subacute, 1000 mg / kg p.o. tau pom tias tsis muaj tshuaj lom, qhia txog kev nyab xeeb ntawm gallic acid.
Puas gallic acid puas zoo rau koj?
Qhov tshwm sim: Ntau qhov txiaj ntsig tau tshaj tawm rau cov kua qaub kua qaub, suav nrog antioxidant, tiv thaiv kab mob, thiab tshuaj tiv thaiv kab mobCov tshuaj no tau tshaj tawm tias muaj cov haujlwm kho mob hauv plab hnyuv, neuropsychological, metabolic, thiab mob plawv.
gallic acid ua dab tsi rau lub cev?
Gallic acid (GA) yog ib qho tshuaj polyphenol tshwm sim nyob rau hauv txiv hmab txiv ntoo, zaub, thiab tshuaj ntsuab. Raws li kev tshawb fawb yav dhau los, GA muaj ntau yam khoom siv lom neeg, suav nrog antioxidant, anticancer, anti-inflammatory, thiab antimicrobial zog.

Puas citric acid voj voog tsim citric acid?
Lub voj voog citric acid - tseem hu ua TCA lub voj voog lossis Krebs lub voj voog - yog cov tshuaj lom neeg cov tshuaj tiv thaiv kom tso tawm lub zog cia los ntawm oxidation ntawm acetyl-CoA tau los ntawm carbohydrates, rog, thiab cov proteins.
Puas citric acid thiab ascorbic acid tib yam?
Thaum ob leeg yog cov kua qaub, lawv tsis zoo ib yamKev tshawb fawb, lawv cov qauv tshuaj sib txawv me ntsis, uas ua rau muaj kev ua haujlwm sib txawv. Citric acid yog acidic ntau dua li ascorbic acid. Yog li ntawd, citric acid tau pom zoo thaum lub kaus mom txiv lws suav kom txo qis pH lossis nce acidity .
Lus dab tsi yog gallic?
