Question

a. Draw the ? and ? cyclic forms of D-psicose and D-mannose. The Powerpoint slides contain the linear structure of D-psicose, but the textbook does not; D-psicose is the carbon 3 epimer of D-fructose. Circle the sugars that are reducing sugars.' b. Draw both possible disaccharides of D-psicose and D-mannose that are joined by an ?(1?4) glycosidic linkage. Are either of them now a reducing sugar?
