Unformatted text preview: Molecules: • Molecular shape imp. to biological recognition Hydrogen Bonds: • Neither ionic or covalent • Relatively weak compared to covalent/ionic bonds Water: • H2O + H2O->H3O+OH- (ionization) • Breaking of covalent bond between O and H and creation of covalent bond of free H with other molecule (hydronium) • H3O referred to as H+ or proton • Very little ionization in pure water • Conc. of H3O+=OH-• Acids -> excess of H3O • Bases -> excess OH • Low pH (0-5) Neutral (5-9) High (9-14)...
