Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

According to Figure 4 and 5‚ the moles of Cu initially obtained and at completion‚ differentiated. It was evident that the initial moles of Cu (0.0254)‚ did not regenerate all the amount‚ as 0.0124 moles of Cu was attained. In regards to this‚ the no. moles that was eliminated was approximately‚ 0.013. Respectively‚ in Figure 3‚ a large deviation amongst the initial and final quantity of copper‚ this implies that the rest of the mass that had diminished‚ was greater than the final product. These

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in

Compared to the technology we possessed before 1980‚ Our technology today is significantly more advanced and it is only the beginning. As the use of technology has increased dramatically in our everyday life many argue that it can be very useful‚ but others can say that technology only seems to be affecting the way Millennials think and process information. Mark Bauerlein is a prime example of this way of thinking‚ he declares that all of those under 30 years of age‚ also known as the Millennials

ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers developed numerous methods to cultivate uncultured organisms in their environment. The goal of this experiment was to find antimicrobials in the uncultured soil. Through this successful experiment‚ the researchers

After reading the rather confusing (and extremely hostile) essay "Shakespeare‚" it’s not hard to tell that the author calls for an eradication of William Shakespeare’s plays from English classrooms. The author feels that many of Shakespeare’s great plays‚ including Macbeth‚ Romeo and Juliet‚ and Twelfth Knight‚ are irrelevant to today’s society. Although the language in this essay is extremely convoluted and tangled‚ as I am sure everyone has noted‚ I believe that I have found the quintessence of

Kant’s Threefold Synthesis and Transcendental Unity of Apperception A large portion of Immanuel Kant’s Critique of Pure Reason concerns itself with explaining how humans are able to attain knowledge‚ especially empirical knowledge of the world. Addressing this question‚ Kant wrote: “We must enquire what are the a priori conditions on which the possibility of existence rests” (A95-96). After problematically deducing that all cognition of objects is limited by the objects’ physical appearances (A95)

Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is a fundamental and important synthesis process in training our future chemists in both commercial and academic employment and principles. By utilizing this method of synthesis‚ the chemist has the knowledge to utilize
