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. ________

EXTRACTION AND ISOLATION OF PROTEINS Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources where we could get proteins. It can be from plants

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.

DENATURATION OF PROTEINS Abstract The experiment aimed to use the concept of viscosity to study the effects of different denaturants on 1% albumin extract. An Ostwald viscometer was used to measure the flow time of 5 mL of the blank and native protein. These were then denatured by adding 1 mL of denaturant and had their flow time measured. The flow time from the blank to denatured protein is increasing. The specific viscosity and reduced viscosity

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

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

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen
