Table 1.
A comparison of the different types of hydrogen bonded interactions in the collagen fibril. The first two columns of data refer to the average number of interprotein attractions per collagen protein in the simulated fibril at any point in time. The final column shows experimental data for equivalent interactions in folded globular proteins recorded by Stickle et al.10 Percentages are shown such that each column sums to 100%.
