Fig. 2.6 Water molecules. In water and other molecules, oxygen keeps the

electrons most of the time. This produces positive (+) and negative (-) regions and

hydrogen bonds. Hydrogen bonds form within and between many body molecules affecting shapes and functions (e.g., DNA, proteins). (For examples, see the following, where hydrogen bonds shown with dotted lines: https://commons.wikimedia.org/wiki/File:DNA_molecular_structure,_showing_individual_nucleotides_and_bonds.jpg; https://commons.wikimedia.org/wiki/File:Alpha_beta_structure_(full).png.)
