Gushyira mu bikorwa D - (+) - FUCOSE
Umubare munini wa fucose muri kamere ni L-fucose, na D-fucose muburyo bwa D ni isukari idasanzwe kandi iboneka muri glycoside.
D-Fucose D-Fucose> 98%.Ubwoko bw'isukari itandatu ya karubone, ishobora gufatwa nka methyl pentose.L-fucose iboneka mu byatsi byo mu nyanja no mu menyo ku bwinshi, kandi iboneka no muri polysaccharide ya bagiteri zimwe.
Nkibigize urunigi rwisukari muri glycoproteine, fucose iragaragara cyane kuri plasma membrane yibice bitandukanye bigize selile.Fucose ifite itsinda rimwe rya hydroxyl kuri atome ya gatandatu ya karubone kuruta isukari rusange ya karuboni esheshatu, bityo fucose ni hydrophilique nkeya na hydrophobique kurusha izindi monosaccharide.Fucose muri molekile zimwe zitsinda amaraso ni ikimenyetso cyitsinda runaka ryamaraso.
Glycans (N-ihuza glycans) igaragara hejuru yinyamaswa z’inyamabere, ingirabuzimafatizo n’udukoko.Fucose monomers irashobora polymerize kugirango ikore fucoidan.L-fucose nuburyo bwonyine bwo kwisi yose muri kamere, na D-fucose ni analogue ya galaktose.
Ibintu bibiri bitandukanya fucose nandi masukari atandatu ya karubone iboneka mu nyamaswa z’inyamabere, ni ukuvuga kubura itsinda rya hydroxyl kuri karuboni esheshatu nuburyo bwa L.
Ubwoko bw'isukari itandatu ya karubone.Kandi irashobora kugaragara nka methyl pentose.Umubare munini wa fucose uri muri kamere ni L-fucose, na fucose hamwe na D iboneza ni isukari idasanzwe kandi iboneka muri glycoside.L-fucose iboneka cyane mu byatsi byo mu nyanja no mu menyo, kandi iboneka no muri polysaccharide ya bagiteri zimwe na zimwe.Nkibigize urunigi rwisukari muri glycoproteine, fucose iragaragara cyane kuri plasma membrane yibice bitandukanye bigize selile.Fucose ifite itsinda rimwe rya hydroxyl kuri atome ya gatandatu ya karubone kuruta isukari rusange ya karuboni esheshatu, bityo fucose ni hydrophilique nkeya na hydrophobique kurusha izindi monosaccharide.Fucose muri molekile zimwe zitsinda amaraso ni ikimenyetso cyitsinda runaka ryamaraso.Ubusanzwe, fucose ikurwa mubyatsi byo mu nyanja, ikabanza kuvurwa na aside, ikabogama, hanyuma igwa mu buryo bwa fenylhydrazone, hanyuma fenilhydrazine ikurwaho kugirango ibone kristu ya α-L-fucose.
