41. Ion-dipole bonding is stronger than hydrogen bonding . 42. It is proposed that such hydrogen bonding interactions imply pterin cyclic ring system as an electron carrier. 43. Sugar dissolving in water relies on hydrogen bonding but again this involves a movement of electrical charge. 44. This means that 2 adjacent residues in the primary structure must form the same hydrogen bonding pattern. 45. Why is water a liquid and not a gass ? well the answer lies in hydrogen bonding . 46. THF or pyridine ) through hydrogen bonding . 47. The solubility of different species in imidazolium ionic liquids depends mainly on polarity and hydrogen bonding ability. 48. This difference is attributed to the effects of hydrogen bonding , which is absent in the gaseous state. 49. This attraction is known as hydrogen bonding . 50. The enantioselectivity is further controlled by hydrogen bonding between the proline carboxylic acid group and the imine.
