I need to provide a well-reasoned response about glucose. The best biochemical description is that glucose is an aldohexose and its C-4 epimer is galactose, while its C-2 epimer is mannose. It’s important to note that glucose is not a ketose, as that refers to fructose. Glucose exists in its D form, not L, and it's a monosaccharide rather than a disaccharide. I could cite some general biochemistry texts for support. Let’s put this together!
