hydrogen bond Definition

hydrogen bond

noun

a weak chemical bond formed through a hydrogen atom, esp. if bridging two similar electronegative atoms or groups from two different molecules

hydrogen bond Usage Examples

Converse of subject

  • link: Two polynucleotides running in opposite directions are linked by hydrogen bonds between the bases forming base pairs.

Converse of object

  • donate: In this context, the number of hydrogen bonds donated is surprisingly high.
  • form: The ester is the only thing in the mixture which doesn't form hydrogen bonds, and so it has the weakest intermolecular forces.
  • make: Move the " other " oxygen to a position at which it can make the appropriate hydrogen bonds.
  • cause: An earlier version of act excluded various N/O and O/O combinations, but this was causing genuine hydrogen bonds to be missed.

Adjective modifier

  • possible: It prints out all the possible hydrogen bonds to any of the three residue types.

Modifies a noun

  • donor: All three hydrogen bond donor groups bind to the anion.
  • parameter: The hydrogen bond parameters ( length, tolerance and max opening angle ) are defined in the squid_param file.
  • group: All three hydrogen bond donor groups bind to the anion.
  • routine: The explicit hydrogen bond routine is slower but more accurate and requires the presence of the polar hydrogen atoms.

Preposition: between

  • molecule: Hydrogen bonds to water molecules ( ie isolated oxygen atoms ) are found, and also hydrogen bonds between water molecules.
