CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C

of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins has also

Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.

Receptor Proteins According to Abedon (2012)‚ receptor proteins are intracellular proteins‚ or protein fractions‚ that have a high specific affinity for binding a known stimulus to cellular activity. Receptor proteins may be located at cell surfaces or within the interior of cells. They may detect hormones or instead keep track of what otherwise is going on in cell ’s environment. They may be enzymes or serve to relay the occurrence of signal reception in other ways such as by opening up ion channels

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon

High-Protein Diets Christine J. Williams SCI 241 September 19‚ 2012 Diane Carson High-Protein Diets Proteins are a vital nutrient that must be provided by one’s diet. Bones‚ skin‚ muscle‚ hair‚ and most other tissues are made up of proteins. The continuous replenishment of new protein from one’s diet keeps the body functioning properly. When a person is consuming a high protein diet‚ it is inevitable to be on a low carbohydrate diet as well. There are a lot of foods that contain protein and

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

Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly
