Benzyne Formation and the Diels-Alder Reaction Preparation of 1,2,3,4 Tetraphenylnaphthalene Aubree Edwards Purpose: 1,2,3,4-tetraphenylnaphthalene is prepared by first producing benzyne via the unstable diazonium salt. Then tetraphenylcyclopentadienone and benzyne undergo a diels-alder reaction to create 1,2,3,4-tetraphenylnaphthalene. Reactions: Procedure: The reaction mixture was created. Tetraphenylcyclopentadienone (0.1197g, 0.3113 mmol) a black solid powder, anthranilic acid ( 0.0482g, 0.3516 mmol) a yellowish sand, and 1,2-dimethoxyethane (1.2 ml) was added to a 5-ml conical vial.
Unknown Lab Report Unknown # 25 By: Jenna Riordan March 19, 2018 Bio 2843 1. Introduction Microbiology is the study of microorganisms found in all different environments throughout Earth, from the hot thermal vents at the bottom of the ocean to the ice at the top of a mountain.
Radioactively Labeled Azole Import by M. oryzae Radioactively labeled FLC (3H-FLC), (481 GBa/mmol, 13 Ci/mmol, 1 µCi/µL; 77 µM FLC) was custom synthesized by Amersham Biosciences. The drug concentration used during the import assay was well below the Minimum Inhibitory Concentration (MIC) for the strain (M. oryzae FLC MIC >32 µg/ml). To directly measure azole intracellular accumulation in the fungal cell, we used 3H-FLC in our drug uptake assay designed for M. oryzae.
Enzymes are proteins that significantly speed up the rate of chemical reactions that take place within cells. Some enzymes help to break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates.
Based on calculations #5 and #6 made above for solving the molecular weight, it was identified that the third unknown volatile liquid was Heptane: 100.20g/mol. Since the observed value was 104.8g/mol, it was assumed that Heptane was the only gas out of all that were listed that shared a similar value. Supported by table 2 and 3 the average molecular weight of acetone and the unknown volatile liquid was calculated to be approximately, 154.5g/mol and 104.8g/mol, respectively. The molecular weight (MW) for both acetone and the unknown volatile liquid was unsuccessfully proven to match the accepted values of 58.08g/mol and 100.20g/mol, respectively. More specifically, this was evident due to the percent error that was calculated, approximately
The main reason for this experiment was to find an effective way to save victims of immersion hypothermia. During this experiment, prisoners were dunked into a tank of ice water. Some had anesthesia and some were wide awake; many were naked. This experiment was done in many different ways, but mostly, the prisoners were dumped in the ice water then were thrown in boiling hot water. About 100 people died during that experiment.
1. Using human as laboratory animals a. True nature of experiment was kept from subjects, to ensure their cooperation. b. The study was meant to discover how syphilis affected blacks as oppose to whites.
The purpose of this experiment is to determine the pattern of
He gave the test subjects another glass of the water. He observed the results.
In that view the experiment achieved its goal. The prisoners revolted, the guard violated the prisoners rights, and the experiment got so out of control that they had to stop after only 6 of the 14 days intended. The experiment was successful in many ways, it proved that the environment
Enzymes are biological catalysts, meaning that they speed up chemical processes in our bodies by lowering the activation energy required for them to take place. Like chemical catalysts, enzymes take place in the reaction, however, remain unchanged at the end. In humans, enzymes are involved in nearly all of the biological processes required for us to live. All known enzymes are proteins, hence are made up from chains of amino acids. They have an active site, which is the part of the molecule where the reaction takes place.
The author of the journal, Andrew Phelvin, discussed the experiment in depth and where the idea had lacked. Phelvin explains
They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.
In doing that, there was a well-rounded amount of research that was gathered to make better sense of the whole experiment. This was an excellent experiment that was done. We never know why we do the things we do; a lot of times of more often than none, it started from our
The main strength of conducting this experiment is that is shows the behavior exactly as it occurs in the real world.
