Starch contains CC, CH, CO, and OH bonds. Hydrocarbons have only CC and CH bonds. Both starch and hydrocarbons can form colloidal dispersions in water. Which dispersion is classified as hydrophobic? Which is hydrophilic? Explain briefly.
A martini, weighing about 5.0 oz (142 g), contains 30.0% by mass of alcohol. About 15% of the alcohol in the martini passes directly into the bloodstream (7.0 L for an adult). Estimate the concentration of alcohol in the blood (g/cm3) of a person who drinks two martinis before dinner. (A concentration of 0.00080 g/cm3 or more is frequently considered indicative of intoxication in a normal adult.)
You are given a protein solution with a concentration of 0.15 mg/ml. Suppose that we want to prepare 1 ml of 10 μg/ml solution. How much of H2O and protein stock do we need to add to obtain the target concentration and volume?
Ethanol is metabolized in most people at a constant rate of about 120mg per hour per kg body weight, regardless of its concentration. If a 70kg person were at twice the legal limit (160mg/100ml), how long would it take for their blood alcohol level to fall below the legal limit?
1. You have a concentrated stock solution of bacterial LPS in water that has a concentration of 1 mg/ml. What is the concentration of a diluted solution with a dilution factor of 1:2? 2. Your stock solution is 1 mg/ml and your final solution is 1ug/ml. What is your dilution factor? 3. A 1 ug/ml solution is diluted so it is half as concentrated as the stock. What is the concentration of the new solution in ng/ml?
A serum calcium concentration is 9.5 mg/dl. Express this in meq/L.
You are given a protein solution with a concentration of 0.15 mg/ml. If the molecular weight of the protein is 22,000 Da, express its initial concentration in moles/liter, μmoles/ml, and μmoles/μl, respectively. If we want 20 μmoles of proteins for a reaction, what volume do we need to prepare?
1: you will make 10ml of 200μg/ml. (Hint: Use C1V1=C2V2) How much 1000μg /ml BSA will you add to make 10mL of 200μg/ml? How much water will you add to this solution? 2 You will make 10ml of 1mg/ml (or 1000μg /ml) of BSA. How much will you weigh (in GRAMS) for 10mL of 1mg/ml?
You are creating a standard curve for a protein experiment. You have to stock solution of BS a and would like to obtain dilutions. Explain how you would create a 1:1000 dilution of your protein stock solution.
