(etc. why do we heat or add chemicals like nacl or ammonium sulphate?) 1)Casein Isolation from MilkExperimental Procedure* Put 100 ml of milk in a 500 ml beaker and heat it to 40 0C. * Also heat 100 ml acetate buffer and slowly add it to the beaker with milk while stirring. * The final pH of the mixture should be 4.8. * Cool the suspension to room temperature and wait 5 more minutes before filtering. * Wash the precipitate several times with small volumes of water and then suspend it in approximately 30 ml of ethanol.Filter the suspension in the buchner funnel and wash the precipitate a second time with a mixture of equal proportions of ethanol and ether. * Finally, wash the precipitate on filter paper with 50 ml of ether and soak and dry. * Make the ether evaporate by spreading the powder. * Weigh the casein and calculate the percentage yield of the protein. * Compare with theoretical yield of 3.5 g per 100 ml milk. 2)Purification of Egg…
- 3 mL of a 45 mM stock solution of a substrate is added to 8 mL of water. Calculate the following values. The substrate molecular weight is 125 g/mol. Calculate the following values: Substrate Volume in mL Dilution Factor Substrate number of moles Substrate concentration for the diluted solution in mM Substrate concentration for the diluted solution in mole/L Substrate concentration for the diluted solution in mg/mLBeer’s law is strictly obeyed only in dilute solutions. Why?Many of the buffers used these days, such asHEPES and PIPES, were developed because they have desirablecharacteristics, such as resisting pH change with dilution. Whywould resisting pH change with dilution be advantageous?
