1 Using Haworth projections, draw the structure of an a-disaccharide of mannose B(1,2) galactose (mannose is the C-2 epimer of glucose, galactose is the C-4 epimer of glucose). Using the disaccharide that you have drawn, show one interaction that would occur between C-4 of galactose and the R-group of His at pH 7. You will need to draw the structure of His. Use a dotted line between the specific atoms to indicate the interaction. What type of interaction is this? O 2022 Arizona State University Online 2.
