In this paper we repo t the discovery of a new flavonoid glycoside; kaempferol- 3-O-AY-D-[34di-p-E-coumaroyl-a-L- rhamnosyl(16)] galactoside (1) and two new mega- stigmanes; (6R 7Z)-910-dihydroxy-47-megastig- madien-3-one (2) (6E)-910-dihydroxy-46-mega- stigmadien-3-one (3) along with three known compounds (6R 9S)-910-dihydroxy-4-megastig- maen-3-one (4) [11] quercetin-3-galactoside (5) [12] and 3'-dimethoxy-564'-trihydroxyflavon (6) [13].
Galectin-3 molecules specifically interact with the galactosides found in MCP (modified citrus pectin).
For example, the secretor FUT2 [fucosyltransferase 2 (secretor status included) (alias, galactoside 2-[alpha]-L-fucosyltransferase 2)] [6] and Le FUT3 [fucosyltransferase 3 (galactoside 3(4)-L-fucosyltransferase, Lewis blood group)] genes control the expression of enzymes in the synthetic pathway that governs expression of critical antigenic saccharide residues and, thus, an individual's presentation of Le blood group structures (28).
The dosage of the Lewis gene [fucosyltransferase 3 (galactoside 3(4)-L-fucosyltransferase, Lewis blood group)] increases the amount of CA 19-9, whereas the dosage of secretor genes decreases it (6).
Neuroprotective effects of salidroside and its analogue tyrosol galactoside against focal cerebral ischemia in vivo and H202-induced neurotoxicity in vitro.
The supernatant containing the CsA-antibody-enzyme complex is then transferred to a measuring cuvette, where it is mixed with chlorophenol red galactoside, which is hydrolyzed by the [beta]-galactosidase to chlorophenol red.
OeB, quercetin-3-glucuronide and quercetin-3-O-(6"-galloyl) galactoside were isolated as described previously (Kiss et al., 2004).
Luciferin phosphate or luciferin galactoside are used as substrates, respectively (12).
3 This project aims to address this gap in available biocatalysts by developing a range of oxidases with distinct and diverse substrates specificity towards common glycans including galactosides, mannosides, lactose, fructose, sialic acids and amino sugars.
They furthermore consist of enzyme inhibitors (trypsin, chymotrypsin), oxalates, saponins, tannins and protease inhibitors, lectins, alpha amylase inhibitors, phenolics, phytates and alpha galactosides [4].
gregaria serum lectins toward [alpha]-linked galactosides is a feature that has also been reported in other acridids, such as L.
