D-GLUCOSE THIAB MONOSACCHARID RELATED raws li cov khoom siv raw

Rau ALKYL POLYGLYCOSIDES

Dhau li ntawm D-glucose, qee cov suab thaj muaj feem xyuam yuav yog cov khoom pib nthuav dav rau kev sib txuas ntawm alkyl glycosides lossis alkyl polyglycosides. Cov lus tshwj xeeb yuav tsum tau ua los ntawm saccharides D-mannose, D-galactose, D-ribose, D-arabinose, L-arabinose, D-xylose, D-fructose, thiab L-sorbose, uas tshwm sim feem ntau hauv cov xwm los yog tuaj yeem ua tau. ua nyob rau hauv industrial scale. Lawv muaj nyob rau ntawm tus nqi qis thiab yog li nkag tau yooj yim raws li raw cov ntaub ntawv rau synthesis ntawm surfactant alkyl glycosides, uas yog alkyl D-mannosides, alkyl D-galactosides, alkyl D-ribosides, alkyl D-arabinosides, alkyl L-arabinosides, alkyl xylosides, alkyl D-fructosides, thiab alkyl L-sorbosides.

D-glucose, tseem hu ua qabzib, yog cov suab thaj nto moo tshaj plaws thiab cov khoom siv organic ntau tshaj plaws. Nws yog tsim los ntawm kev lag luam nplai los ntawm cov hmoov txhuv nplej siab hydrolysis. D-glucose chav tsev yog lub ntsiab ntawm cov nroj tsuag polysaccharide cellulose thiab starch thiab tsev neeg sucrose. Yog li ntawd, D-glucose yog nyob deb ntawm qhov tseem ceeb tshaj plaws cov khoom siv txuas ntxiv dua tshiab rau kev sib txuas ntawm surfactants ntawm kev lag luam.

Hexoses uas tsis yog D-glucose, xws li D-mannose thiab D-galactose, tej zaum yuav raug cais tawm los ntawm cov ntaub ntawv cog qoob loo hydrolyzed. D-Mannose units tshwm sim nyob rau hauv zaub polysaccharides, thiaj li hu ua mannanes los ntawm ivory ceev, guar flours, thiab carob noob. D-Galactose units yog ib qho tseem ceeb ntawm cov mis nyuj qab zib lactose thiab feem ntau pom muaj nyob rau hauv cov pos hniav arabic thiab pectins. Qee cov pentoses kuj nkag tau yooj yim. Qhov tshwj xeeb paub zoo D-xylose yog tau los ntawm hydrolyzing polysaccharide xylan, uas tuaj yeem muab tau los ntawm cov ntoo, straw, lossis plhaub. D-Arabinose thiab L-arabinose yog dav pom raws li cov ntsiab lus ntawm cov pos hniav. D-Ribose yog khi ua ib chav tsev saccharide hauv ribonucleic acids. Los ntawm keto[1]hexoses, D-fructose, ib feem ntawm cane lossis beet qab zib sucrose, yog qhov zoo tshaj plaws-paub thiab nkag tau yooj yim tshaj plaws saccharide. D-Fructose yog tsim los ua cov khoom qab zib hauv ntau ntau rau kev lag luam khoom noj. L-Sorbose muaj nyob rau ntawm kev lag luam nplai raws li cov khoom nruab nrab thaum lub sij hawm muaj kev sib txuas ntawm ascorbic acid (vitamin C).
