4. 5. electrostatic interaction; van der Waals interaction; hydrogen bond; hydrophobic effect; and steric repulsion. None of these five categories of noncovalent forces can be completely separated out from all of the others. Van der Waals interactions continue to play a part in each of the other four phenomena. Hydrogen bonds can be considered as a special case of ionic interactions, and the hydrophobic effect tends to reflect hydrogen bonding in the solvent. Therefore, it is informative to discuss each of these categories separately so as to focus on their unique properties.

Thiols and disulfides undergo rapid exchange and redox reactions. The long side chain of Met is nonpolar. It has a rather flexible side chain containing one sulfur atom in a thioether bond. Met provides the methyl group for many biological methylation reactions via formation of S-adenosylmethionine. 86. g. glycosidases). The free acid can act as a proton donor and the anion can act as a proton acceptor in acid- and base-catalyzed reactions respectively. Asp and Glu are negatively charged residues at physiological pH and are found at protein surface.

Only the bonding electrons move to convert one resonance structure into another. The concept of resonance suggests that if we can draw two or more acceptable structures for a molecular species, then the actual electron does not correspond to any single one of them, but to something between. For this reason these resonance structures are called contributing structures or contributors. The following rules must be observed in using resonance to describe chemical compounds: • Two or more contributing structures comprise a hybrid structure, which approximates the actual molecule.
