Caught up in our busy lives‚ Americans tend to take things for granted and fail to appreciate the little things in life. These little things have big meanings‚ and are much more important than we care to admit. For instance‚ we often pay little attention to small amounts of currency in the form of coins or more specifically‚ pennies.. We bustle around cities and schools and workplaces‚ fishing for cash to purchase a much-needed coffee or snack. Upon arriving to the cash register‚ we scramble

differently with each other‚ again causing the percent yield to change depending on how the contamination affected the substances by producing a higher or lower percent yield. Another source of error could have been due to the transport of the aspirin from the Erlenmeyer flask after cooling to the funnel to be filtered. Some of the aspirin may have been lost or left behind and that would have showed a lower percent

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

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

Mechanism of chalcone formation Kinetic studies have been reported for the base-catalyzed formation of chalcone and its derivatives. [7‚ 8‚ 9] Two alternative mechanisms have been advanced for the reaction of benzaldehyde with acetophenone in the presence of a basic catalyst. 5 The formation of chalcone by the acid catalyzed condensation of acetophenone and benzaldehyde has been studied [10]. The following mechanism seems to be operating- 6 Importance of chalcones [1]They have close relationship

"My house has been destroyed multiple times‚" is the quotes of people who have been affected by tornadoes and hurricanes each year. At up to 150 m.p.h. (Source 4)‚ hurricanes are deadly‚ and definitely with tornadoes who sweep in at a whopping 300 m.p.h. (Source 3)! These storms are life-threatening! Their characteristics‚ cost and damage‚ and their formation have a lot to do with their danger that can approach on you when you least expect it to. If you live in a mid-western state‚ you may be in

Many people in this generation would label themselves as poor‚ but sometimes the line between each class is misunderstood and blurred due to wants instead of needs. Believe it or not there are different levels that describe the underprivileged. Poverty can be divided into about five diverse subgroups‚ which are transitional‚ marginal‚ residual‚ absolute and relative (Carl‚ Page 30). No matter which description of poverty a person may fall into the effects of this social class can be great. A life

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

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

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
