Biochemistry of Proteins; Isolation of Ovalbumin and Enumeration of thiol groups Abstract Thiol groups are important to protein folding and forming disulphide bonds that are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy

Determining the Ksp of Calcium Hydroxide by Titration of Saturated Ca(OH)2(aq) with HCl(aq) Abstract: Titration is a technique that has been used in this experiment to identify the Ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

All cells have the same basic structure (see figure 1) however some cells are specialised to suit a specific purpose. An example of this is the pancreatic beta cells found in the islets of Langerhans. These cells are specialised to synthesise the protein insulin that is involved in the metabolism of glucose in the cells. (Layden‚ 2010) Figure 1 - Picture to show basic structure of a cell. (Farrabee‚ M J. 2007) But how is insulin made? The production of insulin starts in the nucleus which is the

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are

Current status on: Biopharming: crops for the production of Therapeutic & Pharmaceutical proteins Biopharming‚ also known as molecular farming‚ is the production of pharmacologically active substances‚ either induced or increased through the application of genetic engineering. The first instance of artificial gene expression in an organism to produce a pharmaceutical product was the synthesis of insulin in the bacterium E. coli (Goeddel et al.‚ 1979). This type of biotechnology has since moved

Describe how Bacteria decode its genetic information to produce proteins? Intro(10mins) Bacteria belongs to a group of organism that lacks cell nucleus and membrane bound organells. This group of organisms are termed as prokaryotes. Prokaryotes follows the central dogma of molecular biology first proposed by Francis Crick in 1958 to synthesize proteins from mRNA through a process called translation and the mRNA is being synthesized from the DNA by another process called Transcription.

Comp.155 July 24‚ 2013 Jim Henry‚ M.A. High protein diet and exercise versus gastric bypass are two common weight loss approaches that many dieters are choosing. They will be giving you a break down exactly how to keep your diet plan and know what can benefit them or not. Consequently‚ enough both methods come with some form of health related issues. Then they would have sit down and think what something that they could afford economically. In these two approaches does the benefit outweigh
