Nitration of Acetanilide Introduction When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes‚ nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes‚ antioxidants‚ pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors‚ poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical

we have learned in the lab to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed the organisms

Insulin Synthesis The discovery of insulin was one of the greatest events in medical history. The existence of insulin is as necessary as that of glucose (the body’s basic unit of fuel). Both of them are related and required for life. In order for the glucose to be regulated‚ insulin circulates through blood vessels and bind with particular (insulin) receptors‚ promoting interactions essential for the wellbeing of the body’s internal mechanisms. Insulin is a hormone synthesized exclusively

| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing
