The purpose of column chromatography is to separate one compound from another by the differing polarities in the compound. This technique is important in organic chemistry because certain experiments may require the separation of compounds in solution to be used for chemical synthesis and/or analysis of a particular desired product by isolating it. Fluorene is to be separated from 9-fluorenone using the technique of column chromatography. The success of separation and purity is determined with analyzation

How thin is too thin? Liz Harten We see them everywhere we go. While in the waiting room at the doctor’s office‚ on line in the grocery store‚ on our coffee tables and in our mailboxes. Magazines will always be around and will always convey the same messages. “Get pretty now”‚ “How I got thin”‚ “and 25 new diet secrets”. Are you trying to tell us were ugly and fat? Big shot magazines may not be trying to tell us that but it is the idea the young teenage girls have in their heads. There are so

QUALITATIVE TESTS OF CARBOHYDRATES Final Lab Report Submitted by Brittany Fitzgerald 545301 Prepared for Nancy Cook Chemistry 3501 Monday November 26‚ 2012 RESULTS PART A: As a result of the Benedict’s test on various sugar solutions‚ it was found that galactose‚ mannose‚ arabinose‚ ribose‚ lactose‚ fructose‚ maltose‚ and cellobiose tested positively and therefore are considered reducing sugars. Glucose‚ starch‚ sucrose‚ and methyl-D-glucopyranoside on the other hand tested

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be

Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production.

The main purpose of carbohydrate loading is to reestablish both the glycogen of the muscles and liver in order to keep hunger away during some types of competitive sports. These types of competitive sports include: marathons‚ long distance swimming‚ and cycling. Carbohydrate loading is done anywhere from a week out from a competition or event to only twenty four hours before. There are three main benefits to carb loading for athletes of sports like marathons‚ long distance swimming‚ cycling‚ and

Glucose is a form of energy derived from carbohydrates. All living organisms requires energy to live and thrive. When glucose is ingested it is transported through the circulatory system by the various tissues and organs. This glucose will be used by the muscular and nervous system to complete day to day task. If the body is not in need of glucose it will be stored in the form of glycogen for a later date. The entire process starts with carbohydrates‚ for this paper we will be tracing the path of
