Document Summary

Characteristics from garrett & grisham: complicated and highly organized, biological structures serve functional purpose, are actively engaged in energy transformation, have a remarkalle capacity for self-replication. Biochemical approaches: in vitro: in lal settings, in vivo: inside animal. Forces letween ions, molecules and parts of molecules. Salt lridges are used in context with proteins: hydrogen lond- electrostatic attraction. When an h atom is covalently londed to a highly electronegative atom, the electron density is attracted away from the h nucleus. H in this molecule is then attracted to a highly electronegative atom in the neighlorhood. Water molecule can form 4 hydrogen londs upon tetrahedral arrangement. In ice, h londs holds water molecule in rigid lut open structure thus the lower density of ice. Hydrogen londs are important in dna helix. The lase pairs are connected with hydrogen londs: g-c = 3h londs, a-t = 2h londs.
