olfactory GPCR proteins. For each GPCR protein‚ have one control reaction with just the GPCR‚ and one experimental reaction where the GPCR is incubated with the peach extract. Do this for all the olfactory GPCRs. Run all the samples on a gel. If a compound in the peach extract is the ligand for a specific GPCR‚ it will cause a conformational change in that GPCR. This will cause the band on the gel to shift relative to the control reaction for that GPCR. This will allow us to identify which GPCRs are

Identify an unknown carbonyl compound © KCl http://hk.geocities.com/fatherofchemistry Objective To classify a carbonyl compound by a simple test and to identify it by the precipitation of a derivative. Principle In this experiment‚ the unknown compound is either an aldehyde or a ketone from Table 90. In the first part‚ on undergoing Tollen’s & Fehling’s tests‚ ketone will have no reaction. In the second part‚ by preparing a derivative of the compound with 2‚4-dinitrophenylhydrazine

fanilamides and sulfonylureas have advanced our ability to treat diabetes mellitus. Attempts to develop an agent clinically superior to tol butamide by chemical modification have been remarkably difficult in spite of animal human assay. Over 6000 compounds and have been screened for hypoglycemic potency‚ and some structure-activity generalizations are pos sible. Chemicals are made into therapeutic products only in man. Animal screens are often based on a standard marketed product and may lead only

1)Calculate the amount of your compound interest investment after 10 years. Remember that you are starting with $7‚500. $10‚642.83 work: A=7500(1+3.5%/365)^365x10 = 7500(1+0.00009589)^365x10 = 7500(1.00009589)^3650 = 7500(1.419041609) = 10‚642.83 2)Calculate the amount of your simple interest investment after 10 years. Remember to use the same rate and compounding as in #1. $2‚625 work: 7500x.035x10 = 7500x.35=2625 3)Create a graph that shows the growth of your compound interest and simple interest

Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough detail so that someone else in the lab could repeat the experiment. 4. Results and Conclusions. a. Melting point‚ weight‚ and % recovery for each compound. b. Comment on the

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them
