Portage Learning Chem 210 - Module 4 exam. Which of the following monosaccharides is a ketose? Dihydroxyacetone Galactose Glucose Glyceraldehyde Idose Dihydroxyacetone When two carbohydrates are epimers: One is a pyranose, the other a furanose One is an aldose, the other a ketose They differ in length by one carbon They differ only in the configuration about one carbon atom They react differently with iodine THEY DIFFER ONLY IN THE CONFIGURATION ABOUT ONE CARBON ATOM Which pair is anomeric? A) D-glucose and D-fructose B) D-glucose and L-fructose C) D-glucose and L-glucose D) -D-glucose and -D-glucose E) α-D-glucose and β-L-glucose D) -D-glucose and -D-glucose Lactose is made from linking galactose and glucose. When this happens, . Gas is eliminated An anomeric carbon is formed on carbon-1 Water is released An epimer is formed
