Kev Siv
Nws yog ib qho tseem ceeb ua ntej rau kev tsim cov bifidus factors thiab muaj ntau yam tseem ceeb hauv lub cev. Nws yog ib hom tshuaj siv hauv kev kho mob los kho mob rheumatic thiab rheumatoid arthritis. Ua ib qho antioxidant hauv zaub mov, ib qho khoom noj khoom haus rau cov menyuam mos thiab cov menyuam yaus, thiab ib qho khoom qab zib rau cov neeg mob ntshav qab zib.
N-acetylglucosamine yog ib qho tseem ceeb ntawm ntau yam polysaccharides tseem ceeb hauv cov hlwb biological, tshwj xeeb tshaj yog nyob rau hauv exoskeletons ntawm crustaceans, qhov twg nws cov ntsiab lus yog qhov siab tshaj plaws. Nws yog ib qho tseem ceeb precursor rau kev tsim cov bifidus yam thiab muaj ntau yam tseem ceeb physiological functions hauv cov kab mob muaj sia.
Ib qho glucose monomer uas tau muab rho tawm los ntawm cov kab mob uas pom muaj nyob rau hauv cov polymers ntawm cov phab ntsa ntawm cov kab mob, chitin, hyaluronic acid, thiab ntau yam glycans. D-GlcNAc yog siv los txheeb xyuas, sib txawv, thiab piav qhia txog N-acetyl-β-D-hexosaminidases.
NAG muaj cov ntawv thov tseem ceeb hauv ntau yam khoom noj, tshuaj, khoom noj khoom haus, thiab tshuaj pleev ib ce. Nws yog ib hom khoom noj tshiab uas tau txais kev pom zoo los ntawm National Health Commission rau kev siv rau hauv ntau yam khoom noj. Xws li: cov khoom noj mis nyuj: tsim cov khoom noj mis nyuj noj qab haus huv sib koom ua ke nrog mis nyuj protrin. Dej haus: vim lawv cov solubility siab, lawv tsim nyog rau cov kua dej thiab tuaj yeem siv los tsim cov dej haus ua haujlwm. Jelly, khoom qab zib, thiab pastry kuj tuaj yeem siv dav los tsim cov khoom noj ua haujlwm. Tsis tas li ntawd, NAG muaj kev cia siab dav dav hauv kev noj qab haus huv sib koom, kev ua kom tawv nqaij noo, thiab kho, thiab yog cov khoom xyaw zoo rau kev kho mob osteoarthritis thiab kev laus tawv nqaij.
N-acetylglucosamine yog ib qho tseem ceeb ntawm cov polysaccharides tseem ceeb xws li glycoproteins thiab glycolipids hauv cov hlwb ntawm lub cev, thiab nws yog cov khoom siv ntawm chiain. Cov mis nyuj kuj muaj ntau yam oligosaccharides ntawm N-acetylglucosamine. Cov suab thaj no ua lub luag haujlwm tseem ceeb hauv cov kab mob, xws li kev tiv thaiv thiab txhawb nqa lub cev, kev tswj hwm kev tiv thaiv kab mob, kev xa cov ntaub ntawv, kev tiv thaiv kev kis kab mob, thiab kev tiv thaiv kev o.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
