Experiment 13 Questions for Data Analysis and Results Based on the structures shown in Figure 1, rank the four compounds in order of polarity (least polar to most polar). Then state the order of elution from the column (first to elute to last to elute). Recall that a green band was left on the column. […]
Write a formal procedure for this experiment based on what you did in lab, using your values (initial and final masses, etc.).
Organic Chem Formal Lab Report/ Worksheet State the reaction that was done, how the product was purified, and how the product was analyzed. State the percent yield. Draw the overall reaction (not the mechanism). You must come up with the drawing yourself (by hand or electronically). Do not copy it from anywhere. Summarize the chemical […]
Explain what reaction kinetics describe and how the study of kinetics is different from the study of a reaction at equilibrium.

Propose a feasible mechanism for each reaction. Observe the proper construction of reaction mechanisms (arrow positioning, types of arrow heads, lone pair electrons, charges, entry/exit of chemical species, etc.).
ASSIGNMENT Given in each item is a reaction scheme showing the reactant/s, reagent/s, and major product. If the compound shown at the right side is not the major product, rewrite the scheme to show the correct product/s. Propose a feasible mechanism for each reaction. Observe the proper construction of reaction mechanisms (arrow positioning, types of […]
List the types of liquid chromatography (categorized based on separation principles) and briefly describe the principles used for separation for each type.
HW #3 for Chem 318: Analytical Chemistry 2 Solute A has a K = 2.5 for an extraction between water (phase 1) and chloroform (phase 2). If 100 mL of a 0.01M solution containing A in water is extracted one time with 400 mL chloroform, what fraction will be extracted? For the same solute, what […]
What is Vmax and why does the activity plot level off at high substrate concentrations? Provide the chemical structure and 1-2 sentences about each of these reagents as they relate to protein structure, function and/or stability.
CHEM322 Foundations of Chemical Biology Laboratory β-Lactamase: Protein Kinetics and Stability, Week 3 You have now characterized the purity and relative activity of the protein that you purified. This week you will utilize your pooled protein samples to examine two things: Kinetic parameters for the purified enzyme using a continuous enzyme activity assay. Review the […]
Examine protein purity using gel electrophoresis. Generate a protein concentration standard curve and calculate the concentration of your protein solutions.
ASSIGNMENT Use chromatography to purify a protein of interest. Use a colorimetric assays to examine protein activity and folding. Determine the inhibition of several antibiotics with the protein. Determine how various reagents alter the stability/activity of the protein. Examine protein purity using gel electrophoresis. Generate a protein concentration standard curve and calculate the concentration of […]
