There are several derivatives of 13C or 14C glucose that are available for sale from radiochemical supply companies. These labeled compounds are quite useful for metabolic tracer studies. To demonstrate how these are used.
a) Initiate with glucose labeled at C1. Find out where the label is in pyruvate product.
b) Repeat this exercise with the label at position C2 of glucose.
c) Repeat this exercise with the label at position C3 of glucose.
Suppose that one needs 17.65mL of 0.1146M NaOH to titrate 25.00 mL of 0.0237M hydrofluoric acid. Assume no volume change when the salt is dissolved. Calculate the pH of the buffer.
Using the data collected for part B on your data sheet, calculate the molar mass of the unknown acid. Mass of unknown acid is .501g and volume of NaOH used was 17.51mL Unknown acid was dissolved in 50mL of deionized water prior to being diluted wi..
Subtilisin (Mr 27600) is a bacterial protease that can catalyze hydrolysis of certain amino acid esters and amides. Subtilisin does have a problem, in that it becomes inactivated by oxidation of a methionine Met-222. Subtilisin mutant with Cys rep..
What is the pressure drop in lb/in^2 and in atm. What percentage of error is introduced if the density of the air in the manometer leads is neglected
Using kinetic molecular theiry of gases to explain each of the following: a) A container of nonstick cooking spray explodes when thrown into a fire; b) The air in a hot air balloon rise. c) You can smell the odor of cooking onions from far away.
Natural gas is a mixture of many substances, primarily CH4, C2H6, C3H8, and C4H10. Assuming that the total pressure of gases is 1.48atm and that their mole ration is 94:4, 0:1, 5:0.50, calculate the partial pressure in atmospheres of each gas.
40.0 ml of an acetic acid of unknown concentration is titrated with 0.100 M NaOH. After 20.0 mL of the base solution has been added, the pH in the titration flask is 5.10. What was the concentration of the original acetic acid solution. (Ka(CH3COO..
