Glucose is part of the kreb's cycle; sucrose (table sugar) is made up of glucose and fructose. The metabolism of fructose is much more complicated, and ends up producing byproducts that can be linked back to metabolic syndrome. The discussions I've heard about sugar are really more focused on the toxicity associated with fructose and not that of glucose - I think some researchers would argue that fructose consumption is on par with nicotine with respect to ill health effects.
