- Lub luag haujlwm ua Prebiotic & Metabolic Modulator:Raws li ibindigestible disaccharide rau tib neeg, nws mus txog txoj hnyuv lawm. Qee cov kab mob hauv plab muaj txiaj ntsig (xws li,Bacteroidesspp.) muaj qhov tsim nyog -glucosidases rau ferment cellobiose. Qhov fermentation no ua rau luv -chain fatty acids (SCFAs), ua rau muaj peev xwmcov teebmeem prebiotic. Kev tshawb fawb qhia tias kev tswj hwm qhov ncauj ntawm cellobiose tuaj yeem kho cov tsos mob colitis los ntawm kev hloov cov plab hnyuv microbiota thiab txo cov pro- mob cytokine qhia.
- Inducer ntawm Biofilm Dispersal:Qee qhov kev tshawb fawb qhia tias qee yam D- tsim cov suab thaj thiab cov amino acids tuaj yeem ua raws li cov cim qhia txog kev ua rau cov kab mob biofilms disassembly. Txawm tias muaj kev tshawb fawb ntau ntxiv, D-Cellobiose yog qhov txaus siab rau daim teb no rau kev kawm microbial zej zog dynamics.
Cov txiaj ntsig tseem ceeb & qhov zoo
- High Purity & Consistency: Guaranteed purity (>98% HPLC) nrog cov ncauj lus kom ntxaws CoA (Certificate of Analysis), ua kom muaj kev ntseeg siab hauv kev soj ntsuam rhiab thiab kev tshawb fawb txog kev tsim tawm.
- Kev Tshawb Fawb Tseem Ceeb:Ua hauj lwm raws li ib tugqhov tseem ceeb biochemical cuab yeejrau enzymology, microbiology, thiab kev tshawb fawb metabolic, muab kev nkag siab txog cellulose degradation thiab plab microbiome muaj nuj nqi.
- Ntau yam Solubility:Soluble nyob rau hauv dej, ua kom yooj yim npaj cov kev daws teeb meem rau cell kab lis kev cai xov xwm, biochemical buffers, thiab kev kawm pub mis.
- Txhais Carbon Source:Muab lub zog huv, tshwj xeeb, thiab zoo ib yam rau microbial fermentation thiab kab lis kev cai ntawm tes, tshwj xeeb tshaj yog nyob rau hauv cov kev tshawb fawb tsom rau cov metabolism hauv carbohydrate.

FAQ: Cov lus nug nquag nug
Q: Qhov txawv ntawm Cellobiose thiab Maltose yog dab tsi?
A: Ob leeg yog disaccharides ntawm qabzib, tab sis lawv cov glycosidic linkages txawv hauv paus. Cellobiose muaj qhov sib txuas (1 → 4), uas tiv taus tib neeg digestive enzymes. Maltose muaj qhov sib txuas (1 → 4), uas tau yooj yim tawg los ntawm tib neeg maltase. Qhov no ua rau cellobiose tsis yog - qab zib digestible nrog prebiotic muaj peev xwm, tsis zoo li maltose.
