Ukusetyenziswa kwe-D-(+)-FUCOSE
Ubuninzi be-fucose kwindalo yi-L-fucose, kunye ne-D-fucose kwi-D configuration yiswekile enqabileyo kuphela kwaye ifumaneka kwezinye i-glycosides.
D-Fucose D-Fucose>98%.Uhlobo lweswekile enekhabhoni emithandathu, enokuthathwa njenge methyl pentose.I-L-fucose ikhona kwi-seaweed kunye neentsini ngobuninzi, kwaye ifumaneka kwi-polysaccharides yezinye iibhaktheriya.
Njengenxalenye yamakhonkco eswekile kwi-glycoproteins, i-fucose ikhona ngokubanzi kwi-plasma membrane yeendawo ezahlukeneyo zeeseli.I-Fucose ineqela elinye elingaphantsi le-hydroxyl kwi-athomu ye-carbon yesithandathu kuneswekile ye-carbon ezintandathu ngokubanzi, ngoko ke i-fucose ingaphantsi kwe-hydrophilic kwaye i-hydrophobic ngakumbi kunezinye i-monosaccharides.I-Fucose kwiimolekyuli zeqela elithile legazi luphawu lweqela elithile legazi.
I-Glycans (i-N-linked glycans) ikhona kumphezulu we-mammalian, iiseli zezityalo kunye nezinambuzane.I-Fucose monomers inokupholisa ukwenza i-fucoidan.I-L-fucose yodwa ifom yendalo yonke kwindalo, kwaye i-D-fucose i-analogue yokwenziwa kwe-galactose.
Iimpawu ezimbini zahlula i-fucose kwezinye iishukela zekhabhoni ezintandathu ezikhoyo kwizilwanyana ezanyisayo, ezizezi, ukunqongophala kweqela le-hydroxyl kwi-carbon yesithandathu kunye nokwakheka kwayo kwe-L.
Uhlobo lweswekile enekhabhoni emithandathu.Kwaye inokubonwa njenge-methyl pentose.Uninzi lwe-fucose ekhoyo kwindalo yi-L-fucose, kwaye i-fucose ene-D configuration yiswekile enqabileyo kuphela kwaye ifumaneka kwezinye i-glycosides.I-L-fucose ikhona kwiimali ezinkulu kwi-seaweed kunye neentsini, kwaye ifumaneka kwi-polysaccharides yeebhaktheriya ezithile.Njengenxalenye yamakhonkco eswekile kwi-glycoproteins, i-fucose ikhona ngokubanzi kwi-plasma membrane yeendawo ezahlukeneyo zeeseli.I-Fucose ineqela elinye elingaphantsi le-hydroxyl kwi-athomu ye-carbon yesithandathu kuneswekile ye-carbon ezintandathu ngokubanzi, ngoko ke i-fucose ingaphantsi kwe-hydrophilic kwaye i-hydrophobic ngakumbi kunezinye i-monosaccharides.I-Fucose kwiimolekyuli zeqela elithile legazi luphawu lweqela elithile legazi.Ngokuqhelekileyo, i-fucose ikhutshwe kwi-seaweed, iqale iphathwe nge-asidi, ingathathi hlangothi, kwaye emva koko ikhutshwe ngendlela ye-phenylhydrazone, kwaye i-phenylhydrazine isuswe ukuze ifumane i-crystals ye-α-L-fucose.
