Kugwiritsa ntchito D-(+)-FUCOSE
Fucose yambiri m'chilengedwe ndi L-fucose, ndipo D-fucose mu D kasinthidwe ndi shuga wosowa kwambiri ndipo amapezeka mu glycosides.
D-Fucose D-Fucose> 98%.Mtundu wa shuga wa carbon 6, womwe ukhoza kuwonedwa ngati methyl pentose.L-fucose imapezeka m'madzi am'nyanja ndi m'kamwa mochuluka, ndipo imapezekanso mu polysaccharides ya mabakiteriya ena.
Monga chigawo cha unyolo wa shuga mu glycoproteins, fucose imapezeka kwambiri pa plasma nembanemba yama cell osiyanasiyana.Fucose ili ndi gulu limodzi lochepa la hydroxyl pa atomu ya kaboni yachisanu ndi chimodzi kuposa shuga wamba wa kaboni sikisi, motero fucose imakhala yochepa kwambiri ya hydrophilic komanso ya hydrophobic kuposa ma monosaccharides ena.Fucose mu mamolekyu ena a gulu la magazi ndi chizindikiro cha gulu linalake la magazi.
Glycans (N-linked glycans) amapezeka pamwamba pa mammalian, maselo a zomera ndi tizilombo.Ma fucose monomers amatha polymerize kupanga fucoidan.L-fucose ndiye mawonekedwe okhawo padziko lonse lapansi, ndipo D-fucose ndi analogue yopangidwa ndi galactose.
Zinthu ziwiri zimasiyanitsa fucose kuchokera ku mashuga ena asanu ndi limodzi a carbon omwe amapezeka mu nyama zoyamwitsa, ndiko kusowa kwa gulu la hydroxyl pa carbon six ndi kamangidwe kake ka L.
Mtundu wa shuga wa carbon 6.Ndipo imatha kuwonedwa ngati methyl pentose.Unyinji wa fucose womwe ulipo m'chilengedwe ndi L-fucose, ndipo fucose yokhala ndi D kasinthidwe ndi shuga wosowa kwambiri ndipo amapezeka mu glycosides ena.L-fucose imapezeka m'madzi am'nyanja ndi m'kamwa, ndipo imapezekanso mu polysaccharides ya mabakiteriya ena.Monga chigawo cha unyolo wa shuga mu glycoproteins, fucose imapezeka kwambiri pa plasma nembanemba yama cell osiyanasiyana.Fucose ili ndi gulu limodzi lochepa la hydroxyl pa atomu ya kaboni yachisanu ndi chimodzi kuposa shuga wamba wa kaboni sikisi, motero fucose imakhala yochepa kwambiri ya hydrophilic komanso ya hydrophobic kuposa ma monosaccharides ena.Fucose mu mamolekyu ena a gulu la magazi ndi chizindikiro cha gulu linalake la magazi.Kawirikawiri, fucose imachotsedwa m'madzi am'nyanja, poyamba amachiritsidwa ndi asidi, osasunthika, ndiyeno amawombedwa ngati phenylhydrazone, ndipo phenylhydrazine amachotsedwa kuti apeze makristasi a α-L-fucose.
