oligosaccharides

Fructooligosaccharides (FOS) are naturally occurring functional oligosaccharides, which are composed of 2 to 10 fructose molecules combined with glucose molecules. They are widely found in natural plants such as bananas, onions, garlic, chicory, and honey. As a typical prebiotic, fructooligosaccharides cannot be digested and absorbed by the human body, but are selectively fermented by beneficial gut bacteria, especially bifidobacteria, to promote gut health, support microbial balance.

2-Iminothiolane HCl (Trauts reagent) is a useful RNA-protein crosslinking reagent and an effective thiolation reagent for the introduction of sulphydryl groups into oligosaccharides.

GDP-L-fucose disodium, a nucleotide sugar, serves as a crucial substrate for fucose oligosaccharides biosynthesis by providing the fucose moiety. Its formation follows two metabolic pathways: the primary de novo pathway and the secondary remedial pathway [1].

UDP-a-D-Galactose disodium salt is a donor substrate for galactosyltransferases employed in the biosynthesis of galactose-containing oligosaccharides[1].

Sialidase (α2-3-6-8-9) is a broadly specific sialic acid enzyme that cleaves linear and branched non-reducing terminal sialic acid residues from glycoproteins, glycopeptides, and oligosaccharides. It is useful for in vitro and in vivo polysaccharide analysis and characterization, as well as for completing glycoprotein remodeling.

Recombinant endoglycoceramidase II (rEGCase II) is an endo-β-glucosidase that releases intact glycans from the ceramide portion of sphingolipids. It catalyzes the hydrolysis of the β-glycosidic bond between oligosaccharides and ceramide in various sphingolipids.

Recombinant endoglycoceramidase I (rEGCase I) is a glycosidase that facilitates the hydrolysis of β-glycosidic bonds between oligosaccharides and ceramides. Additionally, it catalyzes transglycosylation reactions, transferring the sugar moiety of glycosphingolipids to the primary hydroxyl groups of various 1-alkanols.

Heparinase (Heparinase I) degrades heparin into oligosaccharides or unsaturated disaccharides. It is utilized in the preparation of low molecular weight heparin (LMWH).

Methyl 2,3,5-tri-O-benzyl-β-D-ribofuranoside is a glycosylation reagent used for synthesizing oligosaccharides and polysaccharides.

The compound FA2[3]BG1 & FA2[6]BG1 glycan (G1B), 2-AA labelled is a poly N-glycoprotein functioning as a versatile fluorescent linker. This conjugate is designed with high sensitivity and specificity by mimicking the antennae elements of N-linked oligosaccharides.

FA2[3]BG1 & FA2[6]BG1 glycan (G1B), 2-AB labelled, is a multifunctional fluorescent linker derived from glycan N-linked oligosaccharides, specifically G1F with bisecting GlcNAc. The resulting conjugates imitate the antennary structures of N-glycans, offering high sensitivity and specificity.

β-1,3-N-Acetylglucosaminyltransferase 4 (EC:2.4.1.149, B3GNT4) is involved in the synthesis of poly-N-acetyllactosamine and functions with activity towards type 2 oligosaccharides.

Lysosomal α-Glucosidase (EC:3.2.1.20) is a gamma-amylase specifically acting on glycogen as well as various natural and synthetic oligosaccharides.

Carbohydrate Sulfotransferase 10 (EC:2.8.2.-) catalyzes the transfer of sulfate groups to the 3-position of terminal glucuronic acid residues in oligosaccharides that are attached to proteins and lipids.

Galactose-3-O-sulfotransferase 2 is a sulfotransferase enzyme that acts on oligosaccharides.
