Isolation Have you ever felt isolated from your surroundings‚ either because of language or culture wise‚ being new in town‚ feeling friendless‚ or simply because you have to study while everyone else is out having fun while you study? Well I have had many experiences like those. There was a time in which I had moved from New Jersey to Tennessee and I was the new kid on the block. Also there was another addition in my life

Experiment 55: A Separation and Purification Scheme The final lab report/procedure write-up will consist of the following: Report guide: 1. List the names‚ structures‚ and amounts of each compound in your mixture. 2. Draw a flow chart (like pg 687 in PLKE) showing how you separated and isolated your two compounds. Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough

If you’ve read any of our past blog posts you know that eggs are indeed a perfect source of protein and other essential nutrients. No longer are yolks vilified by “health experts” and we have all been given the green light to enjoy the whole egg. But when it comes time to buy eggs‚ there are so many options it can become confusing to know which is best for our health. There are ‘conventional’ eggs and ‘free range’ and ‘organic’ and ‘pastured.’ What’s the actual difference between all of these and

Effects of Diet on the Development of Cholesterol Gallstones Hannah Matich BIO 392 Dijkstra Thurs 6PM Lab 3/29/17 1 Gallbladder disease is one of the most common gastrointestinal disorders in developed countries. Gallbladder disease is typically manifested in the form of gallstones or gallbladder cancer. Gallstones affect 10-15% of people in developing countries‚ meaning 20-25 million Americans have or will have gallstones (Stinton and Shaffer‚ 2012). Though mortality rate is low;

Isolation and Characterization of Complex Lipids Shea Kathleen Guinto‚ Peter Julius Dale Inocando*‚ SooHyun Jung‚ Jurilla Camille Louise Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment an egg yolk will serve as the sample to isolate lipids and separate them into two classes which is the phosphorylated lipid and the non-phosphorylated lipid. The isolated lipids are then characterized through a series of color chemical tests along with the given

WATER PURIFICATION Introduction Nanotechnology is the manipulation of matter on a near-atomic scale to produce new structures‚ materials‚ and devices. This technology has the ability to transform many industries and to be applied in many ways to areas ranging from medicine to manufacturing. Research in nanoscale technologies is growing rapidly worldwide In the case of nanoscale materials‚ the uncertainties are great because the characteristics of nanoscle materials may be different from those

to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this point the egg could very well bounce. | |

amount of protein‚ and percent yield and an increasing trend for specific activity and fold purification. These trends come about naturally when performing multiple purification steps. To determine the success of each purification step‚ the more important factors to look at are the total activity units‚ total protein amount‚ and percent yield. Looking at our purification table (table 7) our purifications were not very successful. While our total protein followed the normal decreasing trend‚ as

Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90
