WitrynaAlso, hydrogen bonds are stronger, pickier about distance and angle than the alternatives available to other molecules (dipole-dipole, van der Waals etc.) So even if they seem feeble, and even if the alternatives were as plentiful as hydrogen bonds, the latter would still be more capable of tying up molecules. WitrynaWater Molecules: Hydrogen Bonds. Water is of great biological importance. It is the medium in which all metabolic reactions take place in cells. Between 70% to 95% of the mass of a cell is water. As 71% of the Earth’s surface is covered in water it is a major habitat for organisms. Water is composed of atoms of hydrogen and oxygen.
