Document Summary

Define biochemistry and it"s role in living organisms. Outline the material to be covered in this course. The four major classes of biomolecules (carbohydrates, lipids, proteins, & nucleic acid) Besides covalent bonding, the remaining interactions are all electrostatic (based on attraction/repulsion of charges ie electrons) in nature they allow the various biomolecules to interact with each other and themselves. For example, dna structure/replication, protein folding and substrate binding (just a few examples, happens in more things: ionic interactions. Interaction of 2 charged atoms based on coulomb"s law. q1. |______r_____| q2 q = charge on an atom r = distance between atoms. E = dielectric constant (takes into account the medium that the atoms are in) Phosphate is negatively charged, there is electrostatic repulsion of the phosphate groups in the dna backbone (the slide shows ionic repulsion between the negatively charged backbone of dna: hydrogen bonds. A hydrogen atom is partly shared by two electronegative atoms.
