Example text

Once these proteins are folded, it is the accessibility of the various amino acids in the protein and the functional groups present on the surface that determines points of contact and interactions with other biomolecules. Some examples include the formation of a hydrophobic domain that can be inserted into the membrane, an active site for interaction with its specific substrate in the case of enzymes, a leucine zipper or tract of arginine and lysine for interaction with DNA or RNA, and many others.

Notes EXPERIMENT 1 11 E X P E R I M E N T 2 Preparing Buffers at a Specific Molarity and pH SAFETY AND HAZARDS Small quantities of concentrated acids or bases (acetic acid, HCl, NaOH) are required to adjust the final pH of each buffer.

The H+ binding affinity is determined by the equilibrium constant (Kb or Ka), which is specific to each particular buffer reagent. You can essentially think of buffers as molecular sponges that are able to sponge up H+ at various concentrations. Besides maintaining pH value, buffers have other applications, as is the case with phosphate buffered saline (PBS). In addition to dissolving proteins and other biomolecules, the osmolality and ion concentrations of PBS usually match those of the human body, so it is isotonic and nontoxic to cells.
