CARBLOCKS

Modular Representation

of Carbohydrates


This page contains a growing set of carbohydrate partial images for two-dimensional representation of oligosaccharide structures by the Haworth Projection. Look at the Nomenclature and Sterochemistry of Carbohydrates, a part of CARBHYD, for more examples.

Example: Different graphic blocks compose the Haworth projection of Lactose,
or 4-O-(beta-D-galactopyranosyl)-D-glucopyranose.
