Haworth projection: A representation of cyclic carbohydrate molecular structure. The carbohydrate's ring is drawn as if planar, and the substituents points straight up or straight down (perpendicular to the falsely-implied planar ring).

Sample Haworth Projections

α-D-Glucopyranose		β-D-Glucopyranose		β-D-Ribofuranose
