The number of isomers of aldohexose is
Le Bel-van't Hoff rule states that for a structure with n asymmetric carbon atoms, there is a maximum of 2 different stereoisomers possible. As an example, D-glucose is an aldohexose and has the formula C6H12O6. Four of its six carbon atoms are stereogenic, which means D-glucose is one of 2 =16 possible stereoisomers. SpletHerein we propose that the better a template a sugar isomer is for cooperative hydration, the higher its hydration number and protein-protective effect. We developed unique atomistic Monte Carlo (MC) simulation that quantifies energetic and spatial compatibility of sugars with ideal tetrahedral water structure, as embodied in hexagonal ice. ...
