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

Abstract: This experiment synthesized H-Gly-Phe-OH dipeptide using “Fmoc chemistry”. The first part of experiment was the synthesis of L-phenylalanine methyl ester hydrochloride. The methyl ester can be synthesised by reaction of thionyl chloride‚ SOCl2 and dry methanol with L-phenylalanine under reflux condition. The peptide bond was formed later in the experiment‚ where HBTU‚ DiPEA and a solution of Fmoc-Gly-OH in DMF were added to a solution of L-phenylalanine methyl ester hydrochloride in DMF

genes contain the recipes‚ for proteins that make most of the body. Structural proteins form things such as skin‚ hair‚ and muscle. These chromosomes are very long compact coils of DNA (Deoxyribonucleic Acid) that store all the information that the body inbeds such as how one looks and functions. This paper will first describe the structure of DNA; second discuss how the structure of DNA allows it to serve as the basis for inheritance‚ third examine how meiosis allows DNA to be divided into gametes

Computing Computer Science & Engineering DNA Computing Computer chip manufacturers have discovered that sooner or later the physical speed and miniaturization limits of silicon chip is bound to hit a wall‚ therefore they need a new material to produce faster computing speed with fewewr complexity. DNA‚ the material are genes are made of‚ is being used to built the next generation of microprocessor. A nascent technology that uses DNA molecules is to build computers that are faster

Report August 28‚ 2013 DNA Extraction on Onion (Allium cepa) and Human Cheek Cell Arriza‚ Rolland Merch Buscato‚ Carl G. Butil‚ Conrad G. Leonida‚ Renee Theresa ABSTRACT This activity observes the DNA present in onion (Allium cepa) and human cheek cells by extracting it with the addition of lysis buffer and chilled ethanol. The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer degrades the protein enveloping the DNA found in onion and cheek

Protein Article Research SCI/241 August 1‚ 2013 Dr. Theodore Keneklis Protein Article Research Proteins are made up of amino acids‚ and in our bodies we have proteins that “are part of every cell‚ tissue‚ and organ in our bodies” (Centers for Disease Control and Prevention: Protein‚ http://www.cdc.gov/nutrition/everyone/basics/protein.html). There are complete proteins which are made up from animals. These kinds of proteins are found in meat‚ poultry‚ fish and even cheese. A complete

The amazing advances in health science‚ DNA is transforming the way in which criminal investigations and trials are carried out. DNA evidence and its importance can rest on a single fact: Every individual’s DNA is unique. A person’s DNA profile can be used similar to a fingerprint to link suspects to crime scenes and its victims. DNA profiling—which is also called DNA fingerprinting or even DNA typing—has been responsible for overturning verdicts and saving innocent people from execution. The process

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which
