Mаnnоse is а nаturally оccurring sugar that is impоrtant to human metabolism. Mannose can exist in an open chain form (D‑mannose) or can cyclize to form a cyclic structure (α-D‑mannopyranose). Answer the questions below about D‑mannose and α-D‑mannopyranose. Which of the Fischer projections (A-F) below represent D‑mannose? [Fischer] Which of the chair conformations (T-Z) below represent the MOST stable conformation of α-D‑mannopyranose? [chair1] Which of the chair conformations (T-Z) below represent the LEAST stable conformation of α-D‑mannopyranose? [chair2] How many total possible stereoisomers are there for α-D‑mannopyranose (including the one drawn)? [stereopyr] How many diastereomers are possible for D-mannose? [diasman] The anomeric center of a cyclic sugar is the newly formed chiral center resulting from the cyclization reaction. Which of the carbon atoms labeled 1-6 above is the anomeric center? [anomeric] Identify ONE chair conformation (T-Z) that represents the enantiomer of α-D‑mannopyranose. [enantiomer] What is the relationship between the Fischer projections labeled B and D? [relationship]
