HO HLAHALA KA ALKYL POLYGLUCOSIDE

Alkyl glucosides e na le masala a alkyl a hydrophobic a tsoang joala bo mafura le sebopeho sa saccharide sa hydrophilic se tsoang ho D-glucose, tse hokahaneng ka tlamo ea glycosidic.Alkyl glucosides e bonts'a masala a alkyl a nang le liathomo tse ka bang C6-C18, joalo ka li-surfactants tse ngata tse tsoang mefuteng e meng ea lintho, mohlala, li-alkyl polyglycol ethers tse tsebahalang haholo.Sebopeho se hlahelletseng ke sehlopha sa hlooho sa hydrophilic, se entsoeng ka meaho ea saccharide e nang le yuniti e le 'ngoe kapa tse' maloa tse amanang le D-glucose tse amanang le glycosidically.Ka har'a k'hemistri ea tlhaho, li-unit tsa D-glucose li tsoa ho lik'habohaedreite, tse fumanehang hohle tlhahong ka mokhoa oa tsoekere kapa oligo le polysaccharides.Ke ka lebaka leo likarolo tsa D-glucose e leng khetho e totobetseng bakeng sa sehlopha sa li-surfactants tsa hydrophilic, kaha lik'habohaedreite li batla li sa che, li ka nchafatsoa.Alkyl glucosides e ka emeloa ka mokhoa o nolofalitsoeng le o akaretsang ka mokhoa oa bona oa matla.
