Intestinal uptake of dietary glucose and galactose is mediated by the SGLT1 Na+/glucose cotransporter of the brush border. An SGLT1 missense mutation underlies hereditary glucose/galactose malabsorption, characterized by potentially fatal diarrhea; conversely, oral rehydration therapy exploits normal transpor...
These compounds derivatives of 3-glucoside of oleanolic acid are different, from those previously isolated from the flowers of this plant, derivatives of 3-glucuronoside of oleanolic acid. The sugar components of 8 representatives of the new series are glucose and galactose in following ratios: ...
The EPS was composed of glucose and galactose as determined by HPLC and TLC; the protein content was on average 15 ± 5% of EPS dry mass. The solution structure of EPS at different values of pH was revealed by small-angle x-ray scattering. Scattering curves of EPS solutions (0.4%, w/...
Aβ-galactosidase (EC 3.2.1.23, β-D-galactoside galactohydrolase), commonly known as lactase is known to catalyze not only hydrolyze β-D-galactoside linkage of lactose or other β-galactosides into monosaccharides, glucose and galactose but also has transgalactosylation activity to synthesize galac...
Net number of water moleculaes removed就是被移动的水分子百分数,移动得越少说明该糖与水越像(这点用直觉来理解就好) Results suggest that sugars 'fit' into hexagonal ice in the following order: Galactose>Glucose>Mannose>Talose Figure 10 3.Other research: MD simulation ...
The molecular weight of glucoamylase I is 99,000, and that of glucoamylase II is 112,000. Both forms of the glucoamylase contain covalently linked carbohydrate (containing d-mannose, d-glucose, and d-galactose residues) and are therefore glycoenzymes. The carbohydrate-protein linkage in the ...
Glucose is a primary energy source in living cells. The discovery in 1960s that a sodium gradient powers the active uptake of glucose in the intestine1 heralded the concept of a secondary active transporter that can catalyse the movement of a substrate a

Furthermore amino acid substitutions in the SGLT1 of glucose-galactose malabsortion families have been identified. Regions and amino acid residues which are important for the function of the Na+/H+ antiporters (or exchangers) which extrude H+ (in animal cells) or Na+ (in bacterial cells) ...
Lactose is brought into a cell by the lactose phosphotransferase system =-=(21, 35)-=- and is then converted by phospho-,-galactosidase to glucose and galactose 6-phosphate. The glucose is metabolized along the Embden-Meyerhoff pathway, and the galactose 6-phosphate is converted via th......
