D-Galactose

SKU: orb1310463

Description

D-Galactose, a C-4 epimer of glucose, is a natural hexose used to form lactose. It is widely employed in research to induce aging models in animals and is utilized in various in vitro studies of carbohydrate metabolism and glycosylation.

Bioactivity

In Vivo
Chronic D-galactose exposure induces neurodegeneration by enhancing caspase-mediated apoptosis and inhibiting neurogenesis and neuron migration in mice, as well as increasing oxidative damage. Moreover, D-galactose-induced toxicity in mice is a useful model for studying the mechanisms of neurodegeneration and neuroprotective drugs and agents. D-galactose given by oral route leads to cognitive impairments in rats which are accompanied by oxidative damage. Cognitive impairments is observed in the open-field test in the 4th and 6th weeks after d-gal administration, as well as an impairment in spatial memory in the radial maze test after the 6th week of d-gal administration.
In Vitro
Galactose is important for the survival and virulence of bacteria. Galactose is utilized by the Leloir pathway in Escherichia coli. Two anomers of d-galactose are used for different purposes, α-d-galactose as a carbon source and β-d-galactose for induction of UDP-galactose synthesis for biosynthetic glycosylation.
