    The structure and synthesis of TPC is outlined in Scheme 1. Briefly‚ the compound 1 was synthesized as per literature procedure. 2 was synthesized by reacting 1-methy pyrazole-4-boronic pinacol ester with 1 by suzuki-coupling‚ the final product TPC was synthesized by treating with malononitrile in the presence of piperidine as a base and ethanol as solvent. The detailed synthesis procedure given in the experimental section. The structure and purity of TPC was unambiguously confirmed by 1H and 13C

    If I want to target the peptide to different compartments‚ I would use specific signal sequences or uptake-targeting sequences encoded into my peptide. Signal sequences contain information that will target the peptide to a particular organelle. The information is usually encoded within amino acid sequences of the protein itself‚ usually within the 20-50 amino acids. Also‚ each organelle has specific set of receptors that bind only to the specific signal sequences‚ thus making sure of target specificity

    Abstract: The purpose of this lab is to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin)

    Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

    During my junior year‚ I was required to write a synthesis essay about a topic of my choosing. As a woman considering a career in science‚ I researched the gender bias in the science field‚ and why it’s so apparent today. I didn’t realize that I would uncover article after article of individuals undermining the female gender. Ivy League Presidents‚ men with doctorates in Biology‚ and individuals with no background in science alike spread false and harmful information about women. After

    Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells
