Document Summary

Water, weak bonds, and the generation of order out of chaos. Many weak bonds result in large stable structures. Allow for dynamic interactions (hormone binding to a receptor then leaving) and permit energy and information to move about the cell and organism. Brownian motion- the random movement of fluids and gases is powered by thermal noise. Supplies the energy for many of the interactions required for functioning biochemical system. 2. 2 biochemical interactions take place in an aqueous solution. The chemical basis of water"s ability to dissolve so many biomolecules. Water is polar- the charge distribution is uneven. Has the ability to form hydrogen bonds which are continually forming and breaking. Hydrophobic effect- nonpolar molecules do not dissolve in water. Ionic bonds- the interactions between distinct electrical charges on atoms. Form between completely positive and completely negative atoms. E= the force q1 and q2= the charges on the two atoms r= the distance between the two atoms.
