Tšebeliso ea D-(+)-FUCOSE
Bongata bo boholo ba fucose tlhahong ke L-fucose, 'me D-fucose ho D configuration ke tsoekere e sa tloaelehang feela 'me e fumanoa ho li-glycosides tse ling.
D-Fucose D-Fucose >98%.Mofuta oa tsoekere e nang le carbon e tšeletseng, e ka nkoang e le methyl pentose.L-fucose e teng ka metsing a leoatle le marenene ka bongata, hape e fumanoa ho polysaccharides ea libaktheria tse ling.
E le karolo ea liketane tsa tsoekere ho li-glycoprotein, fucose e teng ka bongata lera la plasma la libaka tse fapaneng tsa lisele.Fucose e na le sehlopha se le seng sa hydroxyl ho athomo ea botšelela ea khabone ho feta tsoekere e akaretsang ea khabone e tšeletseng, kahoo fucose ha e na hydrophilic le hydrophobic ho feta monosaccharides tse ling.Fucose ka har'a limolek'hule tse itseng tsa sehlopha sa mali ke letšoao la sehlopha se itseng sa mali.
Li-Glycans (N-linked glycans) li teng holim'a mammalian, lisele tsa limela le likokoanyana.Fucose monomers e ka etsa polymerize ho theha fucoidan.L-fucose ke eona feela mofuta oa bokahohleng oa tlhaho, 'me D-fucose ke analogue ea maiketsetso ea galactose.
Likarolo tse peli li khetholla fucose ho tsoa ho tse ling tsa tsoekere ea khabone tse tšeletseng tse teng liphoofolong tse anyesang, e leng khaello ea sehlopha sa hydroxyl ho carbon six le sebopeho sa eona sa L.
Mofuta wa tswekere ya khabone e tsheletseng.'Me e ka bonoa e le methyl pentose.Bongata bo boholo ba fucose e teng tlhahong ke L-fucose, 'me fucose e nang le sebopeho sa D ke tsoekere e sa tloaelehang feela 'me e fumaneha ho li-glycosides tse ling.L-fucose e teng ka bongata metsing a leoatle le marenene, hape e fumanoa ho polysaccharides ea libaktheria tse itseng.E le karolo ea liketane tsa tsoekere ho li-glycoprotein, fucose e teng ka bongata lera la plasma la libaka tse fapaneng tsa lisele.Fucose e na le sehlopha se le seng sa hydroxyl ho athomo ea botšelela ea khabone ho feta tsoekere e akaretsang ea khabone e tšeletseng, kahoo fucose ha e na hydrophilic le hydrophobic ho feta monosaccharides tse ling.Fucose ka har'a limolek'hule tse itseng tsa sehlopha sa mali ke letšoao la sehlopha se itseng sa mali.Hangata, fucose e ntšoa ho tloha leoatleng, pele e tšoaroa ka acid, e sa nke lehlakore, ebe e kenngoa ka mokhoa oa phenylhydrazone, 'me phenylhydrazine e tlosoa ho fumana likristale tsa α-L-fucose.
