by biliary stasis. Factors that injure the pancreas cause the pancreatic enzymes normally activated in the intestines to now be activated within the pancreas. This is usually caused by one of two things: either a blockage to the pancreatic duct created by gallstones or a reflux of bile acids due to a weakened sphincter. Pancreatic necrosis can be the result of an obstruction to the pancreas. Trypsin, a protein-digesting enzyme, normally activated in the intestines, can become activated in the pancreas

Introduction: The purpose of this study is to find out the nutritional composition of foods that are in an American diet. This lab puts different reagents into different foods and looks at how they react to find what key nutrients it contains. The key nutrients is looking at are vitamin C, Fluoride, Protein, Fat, Sugar, and Starch. There are three questions we are trying to answer through this lab. The first question is; Does food coloring affect the nutritional analyses. The second question

Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

The glucocerebrosidase is an enzyme that gets split by hydrolysis. The chemical glucocerebroside is transitional in the glycolipid metabolism. The glucocerebrosidase is the beta-glucosidic linkage of the glucocerebroside; it is located in the lysosome and also has a molecular weight of Daltons. The Gauchers disease is a disease that is affected by the glucocerebrosidase enzyme due to it not working properly. In the Gauchers disease your organs become much more substantial than normal which usually

Determination of Two Unknown Food Substances: Using Benedict Test, Biuret Test, Iodine Test and Ethanol Emulsion Test Rosezetta E. Jones Germanna Community College Biology 101 Professor Arisa Stritch-Johnson October 21, 2015 Abstract The purpose of this experiment was to identify the two unknown food samples provided. The tests carried out included iodine test for detection of starch presence, Benedict’s test for determination of reducing sugars presence, Biuret test for the detection of

Firstly, we set the membrane builder to obtain exactly 500 glucose carriers. After inserting the membrane into the holder between the two beakers, we then set the glucose concentration of the left beaker to 2.00 Mm and filled the beaker with this. We then filled the beaker on the right with deionized water and began the trial run. Upon setting the timer to 60 minutes, we observed that the glucose equilibrium was reached at exactly 43 minutes. We recorded the data involving the NaCl and Glucose of

The team of homicide investigators has investigated the causal factors of Sean Bean’s death and has been able to identify the contents of Mr. Bean’s stomach by conducting various indicative tests using chemical reagents on the substance. The indicators allowed the team to narrow down the possibilities to find out the contents of Mr. Bean’s last meal. Indicators are chemical reagents that help identify the presence of certain macromolecules in a solution. The team specifically tested for the presence

Enzyme Inhibition Enzyme inhibitors are substances e.g. A drug, toxin, food which inhibits the action of a certain enzyme by inhibiting or decreasing their biosynthesis. Two types of Enzyme Inhibition: 1. Reversible inhibition Inhibitors bind to enzymes through non-covalent bonds, thus dilution of the enzyme-inhibitor complex results in dissociation of the reversibly bound inhibitor. • Competitive inhibition: The enzyme inhibitor and the substrate competes to bind reversibly to the same site of

Enzymes • The secret ingredient in living organism is Catalysis, a process performed by protein enzymes. • Their three-dimensional architecture gives them exquisite specificity to select the substrate molecules to which they will bind and on which they will operate. • The scene of operation called “active site” is usually a groove ,cleft or cavity on the surface of the protein. • Enzyme function frequently occurs many times, and in some cases many thousands of times per second. • The miracle
