Codsiga D-(+)-FUCOSE
Inta badan fucose dabiiciga ah waa L-fucose, iyo D-fucose ee qaabeynta D waa sonkor naadir ah oo kaliya waxaana laga helaa glycosides qaarkood.
D-Fucose D-Fukoose>98%.Nooc ka mid ah lix-kaarboon oo sonkor ah, kaas oo loo tixgelin karo pentose methyl ah.L-fucose waxay ku jirtaa haramaha badda iyo cirridka tiro badan, waxaana sidoo kale laga helaa polysaccharides ee bakteeriyada qaarkood.
Sida qayb ka mid ah silsiladaha sonkorta ee glycoproteins, fucose wuxuu si ballaaran ugu jiraa xuubka balaasmaha ee qaybaha unugyada kala duwan.Fucose waxay leedahay hal koox hydroxyl ka yar atamka lixaad ee kaarboonka marka loo eego sonkorta guud ee lixda kaarboon, sidaa darteed fukoseku wuu ka yar yahay hydrophilic waana ka hydrophobic ka badan monosaccharides kale.Fucose ku jira molecules kooxda dhiiga qaarkood waa calaamade koox dhiig oo gaar ah.
Glycans (N-linked glycans) oo ku yaal dusha sare ee naasleyda, unugyada dhirta iyo cayayaanka.Fucose monomers ayaa polymerize kara si ay u sameeyaan fucoidan.L-fucose waa qaabka kaliya ee caalamiga ah ee dabiiciga ah, iyo D-fucose waa analoogga synthetic ee galactose.
Laba sifo ayaa fucose ka sooca sonkorta lix-kaarboon ee kale ee ku jirta naasleyda, kuwaas oo kala ah la'aanta kooxda hydroxyl ee kaarboon lix iyo qaabaynteeda L.
Nooc ka mid ah lix-kaarboon oo sonkor ah.Oo waxaa loo arki karaa sida pentose methyl ah.Inta badan fucose ka jira dabeecadda waa L-fucose, iyo fucose leh qaabeynta D waa sonkor naadir ah oo kaliya waxaana laga helaa glycosides qaarkood.L-fucose waxay ku jirtaa xaddi badan oo ka mid ah dhirta badda iyo cirridka, waxaana sidoo kale laga helaa polysaccharides ee bakteeriyada qaarkood.Sida qayb ka mid ah silsiladaha sonkorta ee glycoproteins, fucose wuxuu si ballaaran ugu jiraa xuubka balaasmaha ee qaybaha unugyada kala duwan.Fucose waxay leedahay hal koox hydroxyl ka yar atamka lixaad ee kaarboonka marka loo eego sonkorta guud ee lixda kaarboon, sidaa darteed fukoseku wuu ka yar yahay hydrophilic waana ka hydrophobic ka badan monosaccharides kale.Fucose ku jira molecules kooxda dhiiga qaarkood waa calaamade koox dhiig oo gaar ah.Caadi ahaan, fucose waxaa laga soo saaraa geedo badda, marka hore waxaa lagu daaweeyaa aashito, waa la nadiifiyaa, ka dibna lagu shubaa qaabka phenylhydrazone, iyo phenylhydrazine ayaa laga saaraa si loo helo crystals α-L-fucose.
