CHARACTERIZATION OF PROTEINS Abstract Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase‚ 1.03 g egg white albumin‚ and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine the protein concentration

Protein in the Digestive System Taylor Adams Biol 112- 501 18 April 2016 Introduction Proteins are found in nearly all foods that we eat. Once the food we eat makes its way to our stomachs‚ pepsinogen is released from chief cells. This enzyme mixes with hydrochloric acid in the stomach and begins to break down the proteins. Along with the stomach‚ the small intestine is also an important location for protein breakdown. The proteins from both locations are broken down into amino

Protein and Amino Acid Supplementation in Sports The popularity of increasing the “performance-enhancing” supplements‚ Protein and amino acids‚ has flourished among all athletes. This increase is attributed to the belief by many of the athletes that it provides endurance‚ strength and speed enhancement. Amino Acids (AA) enhanced physical feats‚ improved energy and recovery sooner from fatigue. The three vital Amino Acids which were given a high focal point among athletes are leucine‚ isoleucine

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Specificity of Protein-Ligand Binding 1). One can conclude that Orange G. has the lowest affinity for the albumin. In the experiment the concentration of Orange G that binds to protein was a lot less than either Ponceau S. or Bromophenol blue. The ligand with the highest affinity to BSA was a little more difficult to decipher. The experiment shows that all of the 2 µL of both Ponceau S. and Bromophenol blue bind to the BSA. However‚ when 5 µL of the ligand is added the BSA is saturated and cannot

An Le Foundation Biology lab BRADFORD PROTEIN DISCUSSION ESSAY The appearance of blue color showed the present of protein in the BSA dilutions. The more diluted the solution was‚ the less blue it was. The R2 value of the standard curve of BSA dilution was obtained to be 0.9972‚ which is close to 1. The closer to 1 the R2 value was‚ the more accurate the linear portion was. The error percentage of each unknown was large: 25.9% for skim milk‚ 95% for soy sauce‚ and 64.7% for egg white. The vast

of a functional recombinant fusion protein via the directional sub-cloning of an E.coli derived tyrosine phosphatase gene (wzb) into a pT5(6H)CFP mutant expression vector. Abstract: Application of fluorescent fusion proteins to the field of expression and interaction proteomics as a means of dynamic imaging proteins in vivo has allowed for rapid advancements in biotechnology research. Production of such proteins first involves the insertion of a given protein-coding gene transcriptionally in-frame

To examine three different ways of denaturing proteins. HypothesisIt was predicted that the physical characteristics of the egg white solution at room temperature would appear clear and normal like a raw egg white. This is because nothing would be done to the egg white. It was also predicted that when the egg white solution gets heated‚ the protein would denature if the temperature exceeds 65 °C. The protein would solidify‚ turn opaque‚ and turn white in colour. This would happen because the heat
