In this study, we focused on the neuro-behavioral profile, toxicity, and possible mechanisms of action of Dorema ammoniacum gum essential oil (DAG-EO). For this purpose, passive avoidance and Y-maze tests were performed to evaluate the potential effect of DAG-EO in the attenuation of memory impairment induced by 49 days administration of D-galactose and acute injection of scopolam...

Purpose: Determination of changes of glycoconjugates, which have special terminal sugars, in embryonic developmental processes of brain stem and trigeminal nucleus in Balb/C mouse. Materials and Methods: In this study mice embryos between 10-17 embryonic days were used. They were fixed according to ordinary laboratory procedures. The specimens were embedded in paraffin and serial sections with...
The interaction of OH(-) with the sugar β-D-galactose is studied computationally, with Ab Initio Molecular Dynamics (AIMD) as the prime tool. The main findings are: (1) the OH(-) abstracts a proton from the sugar in a barrier-less process, yielding H(2)O and a Deprotonated beta-d-Galactose anion, (Dep-beta-D-G)(-). (2) This reaction can be reversed when two additional H(2)O molecules are presen...
Galactose mutarotase plays a key role in normal galactose metabolism by catalyzing the interconversion of beta-D-galactose and alpha-D-galactose. Here we describe the three-dimensional architecture of galactose mutarotase from Lactococcus lactis determined to 1.9-A resolution. Each subunit of the dimeric enzyme displays a distinctive beta-sandwich motif. This tertiary structural element was fir...
The mold Polyporus circinatus produces an extracellular oxidase that catalyzes the oxidation of n-galactose (1). The reaction appears superficially to be similar to the oxidation of n-glucose catalyzed by notatin (2)) and can be followed by measuring the consumption of oxygen or the production of Hz02 (1). The enzyme is useful for the determination of galactose, employing the same peroxidase-ch...
The crystal structure unequivocally confirms the relative stereochemistry of the title compound, C(6)H(11)FO(5). The absolute stereochemistry was determined by the use of d-galactose as the starting material. The compound exists as a three-dimensional O-H⋯O hydrogen-bonded network with each mol-ecule acting as a donor and acceptor for four hydrogen bonds.
