DENATURATION OF PROTEINS Abstract The experiment aimed to use the concept of viscosity to study the effects of different denaturants on 1% albumin extract. An Ostwald viscometer was used to measure the flow time of 5 mL of the blank and native protein. These were then denatured by adding 1 mL of denaturant and had their flow time measured. The flow time from the blank to denatured protein is increasing. The specific viscosity and reduced viscosity

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds‚ the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen

The Washington State Three-Strikes Law It is difficult to determine whether the three-strikes law in Washington is an effective form of legislation. In 1993‚ Washington was the first state in the nation to adopt three-strikes legislation which imposed a mandatory life sentence without the possibility of parole for persons convicted for a third specific violent felony. The action was fueled by the highly publicized death of Diane Ballasiotes‚ who was raped and murdered by a convicted rapist who

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

Drone Strikes: Death From Above The war in Afghanistan has proved to be very costly. With budget cuts being enforced with the financial meltdown‚ the Department of Defense is looking for a cheaper alternative to fight the war on terror. This is where drones and other sophisticated autonomous military hardware come into play. One such military platform that has proved its efficiency to combat terrorism is the drone. A drone being a unmanned air vehicle such as the Predator currently used in Afghanistan
