Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Table of Reagents: Name Chemical formula Melting Point Boiling Point Density Safety Hazards Diethyl ether C4H10O -116.3°C 34.6°C 0.7134 g/ml Flammable Bromobenzene C6H5Br -30.6°C 156°C 1.5 g/ml

Introduction: Macromolecules are necessary for every living organism to survive. Macromolecules consist of carbohydrates; proteins; lipids; and nucleic acids. The purpose of this project was to find out how macromolecules help your body function. Two weeks ago‚ I recorded everything that I consumed for 7 days. I recorded all of this data on a food tracker. This food tracker listed the amount of grains; vegetables; fruits; dairy; and proteins that I ate. Carbohydrates: You need carbohydrates in

Milk is the probably the most nutritionally complete food found in nature. Whole milk contains vitamins (principally thiamine‚ riboflavin‚ panthothenic acid and vitamins A‚ B12 and D)‚ minerals (calcium‚ sodium‚ phosphorus‚ potassium‚ and trace minerals)‚ proteins (which include all the essential amino acids)‚ carbohydrates (mostly lactose)‚ and lipids (fats). Whole milk is an oil in water emulsion‚ containing approximately 4% fat dispersed as very small (micron sized) globules. The fat emulsion

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the
