Ukusetshenziswa kwe-D-(+)-FUCOSE
Iningi le-fucose ngokwemvelo i-L-fucose, kanti i-D-fucose ekucushweni kuka-D ingushukela oyivelakancane kuphela futhi itholakala kwamanye ama-glycosides.
I-D-Fucose D-Fucose >98%.Uhlobo lukashukela olunekhabhoni eyisithupha, olungathathwa njenge-methyl pentose.I-L-fucose ikhona olwandle nasezinsinini ngobuningi, futhi itholakala kuma-polysaccharides amanye amagciwane.
Njengengxenye yamaketanga kashukela kuma-glycoprotein, i-fucose ikhona kabanzi kulwelwesi lwe-plasma lwezindawo ezihlukene zamaseli.I-Fucose ineqembu elilodwa elincane le-hydroxyl ku-athomu yekhabhoni yesithupha kunoshukela ojwayelekile wekhabhoni eyisithupha, ngakho-ke i-fucose ayinayo i-hydrophilic futhi ine-hydrophobic kakhulu kunamanye ama-monosaccharides.I-Fucose kuma-molecule eqembu elithile legazi iwuphawu lweqembu elithile legazi.
Ama-Glycans (N-linked glycans) akhona ebusweni bezilwane ezincelisayo, amaseli ezitshalo nezinambuzane.Ama-Fucose monomers angakwazi ukwenza i-polymerize yakhe i-fucoidan.I-L-fucose iwukuphela kwefomu lendawo yonke emvelweni, kanti i-D-fucose iyi-analogue yokwenziwa ye-galactose.
Izici ezimbili ezihlukanisa i-fucose komunye ushukela wekhabhoni eyisithupha etholakala ezilwaneni ezincelisayo, okungukuthi ukuntuleka kweqembu le-hydroxyl ku-carbon six kanye nokumiswa kwalo kwe-L.
Uhlobo lukashukela oluyikhabhoni eyisithupha.Futhi ingabonakala njenge-methyl pentose.Iningi le-fucose ekhona ngokwemvelo yi-L-fucose, futhi i-fucose enokumiswa kuka-D ingushukela oyivelakancane kuphela futhi itholakala kwamanye ama-glycosides.I-L-fucose ikhona ngamanani amakhulu olwandle nezinsini, futhi itholakala kuma-polysaccharides amagciwane athile.Njengengxenye yamaketanga kashukela kuma-glycoprotein, i-fucose ikhona kabanzi kulwelwesi lwe-plasma lwezindawo ezihlukene zamaseli.I-Fucose ineqembu elilodwa elincane le-hydroxyl ku-athomu yekhabhoni yesithupha kunoshukela ojwayelekile wekhabhoni eyisithupha, ngakho-ke i-fucose ayinayo i-hydrophilic futhi ine-hydrophobic kakhulu kunamanye ama-monosaccharides.I-Fucose kuma-molecule eqembu elithile legazi iwuphawu lweqembu elithile legazi.Ngokuvamile, i-fucose ikhishwa ogwini lwasolwandle, kuqala iphathwe nge-asidi, ingathathi hlangothi, bese idlula ngendlela ye-phenylhydrazone, futhi i-phenylhydrazine ikhishwa ukuze ithole amakristalu e-α-L-fucose.
