31. In the absence of hydrogen bonding , steric effects direct peroxide addition to the opposite face. 32. In addition to hydrogen bonding , stacking interactions are an important component of these tertiary interactions. 33. :To clarify, hydrogen and oxygen tend to attract each other ( see hydrogen bonding ). 34. The first is the stabilization of the transition state as a result of the hydrogen bonding . 35. The core of the barrel consists of an extended hydrogen bonding network of highly conserved residues. 36. However, utilizing hydrogen bonding often limits the range of pore sizes available due to close packing. 37. Because of hydrogen bonding , alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. 38. In nucleic acids, the secondary structure is defined by the hydrogen bonding between the nitrogenous bases. 39. At this scale, electrostatic and / or Van der Waals and hydrogen bonding forces become significant. 40. :The water molecules are pulled by hydrogen bonding to get to the stable configuration of ice.
