1. Draw glucose B-D-glucose in a chair form, and circle the anomeric carbon. Why is the anomeric carbon significant? 2. Why is cyclization of sugars important? What does the concept of mutarotation indicate to us about dual roles of monosaccharides? Two part question: 3. Why are monosaccharides most commonly found in pyran and furan ring forms, rather than: A) other ring motifs -(think along the lines of: why NOT 3,4, or 7 membered rings)? B) in their linear form? 4....
