We present an exploration of proton transfer dynamics in a monosaccharide, based upon ab initio molecular dynamic (AIMD) simulations, conducted "on-the-fly", in β-d-galactose-H(+) (βGal-H(+)) and its singly hydrated complex, βGal-H(+)-H2O. Prior structural calculations identify O6 as the preferred protonation site

α-D-Galactopyranosides were synthesized and their inhibitory activities toward the Debaryomyces hansenii UFV-1 extracellular and intracellular α-galactosidases were evaluated. Methyl α-D-galactopyranoside was the most potent inhibitor compared to the others tested, with K(i)(') values of 0.82 and 1.12 mmolL(-1), for extracellular

An arabinogalactan with a high content of 3-O-methyl-D-galactose residues has been isolated from the aerial parts of sage (Salvia officinalis L.). Structural studies of the polymer indicated a beta-1,6-D-galactopyranose backbone in which at least one-third of D-galactopyranosyl residues carries methoxyl

The L-arabinose binding protein (ABP) of Escherichia coli naturally binds L-arabinose and D-galactose with very high affinity and, with reduced affinity, a variety of other sugars that differ only at the C5 position of the pyranose ring. However, there are
