Comments | The 393 water molecules near the protein surface have a mean volume of 24.5Å^3 with >90% between 20 and 30Å^3. This value is ~18% less than the volume of a molecule in bulk water (29.7Å^3) but still considerably larger than the van der Waals volume of an isolated water molecule (11.5Å^3, assuming a 1.4Å radius). For volume of 19.51Å^3 type in "water" then click on "calculate properties" and then click on "calculate geometry" at link See BNID 103763, 106549 |
