N-acetyl Glucosamine | 7512-17-6
Product Description:
N-acetyl-D-glucosamine yog ib hom tshuaj biochemical tshiab, uas yog cov khoom siv ntawm ntau yam polysaccharides hauv lub cev, tshwj xeeb tshaj yog cov ntsiab lus exoskeleton ntawm crustaceans yog siab tshaj. Nws yog ib qho tshuaj kho mob rau kev kho mob rheumatism thiab rheumatoid mob caj dab.
Nws tseem tuaj yeem siv los ua zaub mov antioxidants thiab cov khoom noj ntxiv rau cov menyuam mos thiab cov menyuam yaus, cov khoom qab zib rau cov ntshav qab zib.
Kev ua tau zoo ntawm N-acetyl glucosamine:
Nws yog tsuas yog siv los kho cov kev ua haujlwm ntawm tib neeg lub cev tiv thaiv kab mob, inhibiting kev loj hlob ntawm cov qog nqaij hlav cancer lossis fibroblasts, thiab inhibiting thiab kho mob qog noj ntshav thiab qog nqaij hlav malignant. Kev mob pob qij txha kuj tuaj yeem kho tau.
Immunomodulation
Glucosamine koom nrog cov piam thaj metabolism hauv lub cev, muaj dav hauv lub cev, thiab muaj kev sib raug zoo nrog tib neeg thiab tsiaj txhu.
Glucosamine koom nrog kev tiv thaiv lub cev los ntawm kev sib txuas nrog lwm yam khoom xws li galactose, glucuronic acid thiab lwm yam tshuaj los tsim cov khoom tseem ceeb nrog rau kev ua haujlwm lom neeg xws li hyaluronic acid thiab keratin sulfate.
Kho Osteoarthritis
Glucosamine yog ib qho khoom noj tseem ceeb rau kev tsim ntawm tib neeg cov pob txha mos, cov khoom siv tseem ceeb rau kev sib txuas ntawm aminoglycans, thiab cov ntaub so ntswg ntawm cov pob txha noj qab haus huv.
Nrog lub hnub nyoog, qhov tsis muaj glucosamine hauv tib neeg lub cev ua rau hnyav dua, thiab cov pob txha pob txha txuas ntxiv mus degrade thiab hnav tawm. Ntau qhov kev tshawb fawb kho mob hauv Tebchaws Meskas, Tebchaws Europe thiab Nyij Pooj tau pom tias glucosamine tuaj yeem pab kho thiab tswj cov pob txha mos thiab txhawb kev loj hlob ntawm cov pob txha mos.
Antioxidant, tiv thaiv kev laus
Glucosamine tuaj yeem ua tau zoo chelate Fe2+, thiab tib lub sijhawm tuaj yeem tiv thaiv lipid macromolecules los ntawm kev puas tsuaj los ntawm hydroxyl radical oxidation, thiab muaj peev xwm antioxidant.
Antiseptic thiab antibacterial
Glucosamine muaj cov nyhuv antibacterial pom tseeb ntawm 21 hom kab mob uas feem ntau pom hauv cov zaub mov, thiab glucosamine hydrochloride muaj cov tshuaj tua kab mob pom tseeb tshaj plaws ntawm cov kab mob.
Nrog rau qhov nce ntawm cov concentration ntawm glucosamine hydrochloride, cov tshuaj tua kab mob maj mam ua kom muaj zog.
