1 of 2 Organic Chemistry II Week 11 worksheet Not for credit For each of these aldoses, identify the number of carbons and number of chiral centers: D-Glyceraldehyde D-Galactose D-Ribose D-Glucose D-Xylose Draw Fischer projections of D-Glucose and L-Glucose: Draw the Haworth projection and chair conformation of β -D-Glucopyranose (draw these based on the Fischer projection above and then compare to those shown in your book): Draw the Haworth projections and chair conformations of α -D-Glucopyranose: The Fischer projection of D-Mannose is below. Use it to draw the Haworth projection and chair conformation of β -D- Mannopyranose: CHO HO H HO H H OH H OH CH 2 OH Draw the Haworth projection of β -D-Mannofuranose:
