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

Poetry can be used as a way of transforming experience and emotions into words‚ which often details personal and intimate feelings that allow the reader to have a taste of what the poet felt in that vulnerable moment. However‚ being a poet often means your work is published and open to the scrutiny and opinions of the public. Thereby turning a once personal experience into a public spectacle. This can either unify reader and author in the comfort that someone else has gone through the same experiences

In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible

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

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)

Safety Precautions for Synthesis of Acetic Anhydride Acetic Anhydride Acetic anhydride is an irritant and also flammable‚ therefore gloves and goggles should be worn at all times during the experiment. It is reactive to water‚ so in the case of fire‚ alcohol foam or carbon dioxide is preferred to use as an extinguisher. This chemical has harmful fumes and use of a fume hood is strongly recommended.

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed
