PAPER and COLUMN CHROMATOGRAPHY REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids.

4A.2 RRL 4A.2.1 Coagulation of Proteins Coagulation of protein refers to sticking together‚ like a blood clot‚ usually as a result of denaturation or coming out of solution due to abnormal ionic strength or a change of solvent. Definite characteristics of the proteins are changed when they are coagulated‚ among which is loss of solubility in water and dilute salt solutions. In some instances and under certain conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2

Discovered in 1838‚ proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential for their functioning. In other words proteins are the building blocks of life. They do many tasks for the human body and other organisms‚ that could not be done individually. These macromolecules could function as structural proteins and form structures such as keratin in hair‚ teeth‚ bones‚ muscles‚ collagen in connective tissues‚ horns in animals

Abstract This experiment aimed to study the effect of various denaturants on albumin and casein protein extracts through viscosity measurements. 5 mL samples of native and denatured protein solutions were prepared‚ using -mercaptoethanol‚ urea and SDS as denaturants for albumin‚ and NaOH‚ NaCL‚ HCL‚ -mercaptoethanol‚ urea and SDS for casein. 5 mL blank solutions for each denaturant used were also prepared. The viscosity of the solutions were determined using Ostwald viscometer. ________

experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as contractile proteins‚ enzymes

exchange Chromatography Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography‚ in which positively charged ions bind to a negatively charged resin; and anion exchange chromatography‚ in

BASICS OF INTEREST RATE SWAPS A swap is an agreement between two institutions to exchange future cash flows. Suppose there is a bank receiving fixed 8% return on 2 year money lent. This bank can swap its revenue stream against another firm’s variable rate 2 year money. In practice swaps tend to be more complicated and can involve more simultaneous variations of interest rates and currency as well. When settled‚ only the differential between the would-be payments are exchanged between two parties

Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure include; IR spectroscopy‚ thin layer chromatography (TLC)‚ and CHN analysis. A radical copolymerization reaction was conducted‚ with the initiation by radical initiator 1‚1’-azobiscyclohexanecarbonitrile. CHN analysis‚ IR spectroscopy‚ and Proton NMR analysis were used to prove its composition

What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying
