POLYS GLYCAN BUILDER : A user friendly tool to build 3D structures of complex glycans and polysaccharides

QUICK HELP : Monosaccharides are grouped into families (algea, bacteria, GAG, N-O- linked glycans, plants, virus, conjugates, ...)
1. Select a family, 2. Drag & Drop monosaccharides , 3. Build the structure, 4. Vizualize it / Download it. More
