3D Modelling Overview
We built 3D models to see how changing parameters such as branching degree and the number of tiers affect the overall structure of the molecule in a chemically accurate way.
Glycogen
Glycogen is a polysaccharide composed of glucose units linked by alpha-1,4 glycosidic bonds. Each linear chain contains approximately 13 glucose residues and a number of alpha 1-6 glycosidic bonds, which allow branching, that are 3–4 residues apart.
This simple model - created for our wiki by the SWEET software - shows a small section of a glycogen molecule consisting of 91 glucose units which are contained within 7 branches and 3 tiers. The 1,4 linked sections can be seen to coil into a helical shape, and the 1,6 linkages form helical branches away from the centre of the molecule.
You can interact with the model using your mouse.
