Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation (Salting Out)  crude ovalbumin was isolated from egg whites of two medium-sized eggs. Egg whites contain about 88.5% water and about 10% proteins, from which ovalbumin is the major component. The eggs were cracked open, and the egg whites were separated carefully from the yolk. Stirring of the egg whites was done to break up the membrane. This was followed by filtration through cheesecloth, where a clear filtrate was obtained. About 40.0 mL of the filtered undiluted egg white was measured, and 0.10 mL of 1 M acetic acid was slowly added for every 1.0 mL of egg white with constant stirring. A turbid mixture with few amounts of white precipitate may be expected to form. These may be removed by filtering the mixture using a cheesecloth. After filtration, 30.0 mL of the filtrate was obtained, and the solution was brought from 0% to 40% saturation by adding the required amount of powdered ammonium sulfate,…

List the differences and similarities between prescription and over-the-counter (OTC) medicines. Next, list what both types of medicines have in common.

The avg. toxicity of animal-based foods is about 0.4pg (picogram) of TCDD equivalent per 1g of food, and the LD50for 2,3,7,8 - TCDD is about 0.001 mg per kg of body weight. What mass, in kg, of animal-based food would you have to consume to ingest a fatal dose of it? (Assume your body mass is 60 kg.)

Calculate the one-day administered mL of amoxicillin suspension for otitis media for a 18-month-old child weighing 29.1 lb. The dose needed is 40. mg/kg and the suspension comes in a concentration of 400. mg/5.0 mL.
