Document Summary
The left and right projections are coming out of the page. The top and bottom are going into the page. Pretty much all the sugars in this course are d. In a monosaccharide there will always be one carbon with a 2 bonds to oxygen. D means right the -oh group one the highest number chiral carbon will be on the right side in the fischer projection. 2 isomers that only differ due to one stereocenter. Aldoses (c=o on the end) vs ketose (c=o in the middle) Use a haworth projection to represent cyclized monosaccharides. Note: although the haworth projection looks planar the ring structure is not flat in reality. To convert a fischer projection to a haworth projection. Take carbon 1-4 and use them as the front of the ring. Rotate the fp 90 to the right. The substituents on the bottom will be on the bottom of the ring, and vise versa for the ones on the top.
