Stochastic modelling of a three-dimensional glycogen granule synthesis and impact of the branching enzyme
Fig 5
Simulated glycogen granule structures for different elongation to branching ratios (Γ).
50,000 glucose units are incorporated. Top: 3D structures of glycogen granules. Blue spheres represent the glucose units, green spheres the non-reducing ends. When Γ = 0.2, the structure of the granule is tightly packed. For Γ = 10.0, the structure of the granule is sparsely packed. Bottom: Associated chain length distributions. The light grey histogram shows the CLD for the tightly packed granule, while the black one shows that of the sparsely packed granule. The inset shows the full range of DP for Γ = 10.0. The longest chain is found to have a DP of 226.
