A Database of Polysachharide 3D structures

By A. Sarkar & S. Pérez


Search for Polysaccharides

PolySac3Db© allows searching for structures in two distinct modes, namely -

1. Discover : Introduces the polysaccharide family to the user before presenting its structure.

2. Expert : Re-directs the expert to the abstract & structural details of the respective polysaccharide (by-passing the introduction).
