1) Draw a chromatogram depicting separation of proteins 1, 2, and 3 (protein #1, mw 30,000, protein #2, mw 60,000, and protein #3, mw 90,000). b)Indicate on the chromatogram in (a) where insulin would elute. Would insulin have total accessibility, some accessibility or no accessibility to the particle pores on this column? c)Referring to the size exclusion chromatogram in (a), indicate on the chromatogram where you would expect a molecule with a size of 40,000 to elute. Would you expect the molecule to be well resolved, somewhat resolved, or not resolved from the peak for protein #1?
Pepsin is the name given to a mix of several digestive enzymes secreted (as larger precursor proteins) by glands that line the stomach. Theseglands also secrete hydrochloric acid, which dissolves the particulate matter in food, allowing pepsin to enzymatically cleave individual protein molecules. The resulting mixture of food, HCl, and digestive enzymes is known as chyme and has a pH near 1.5. What pI would you predict for the pepsin proteins? What functional groups must be present to confer this pI on pepsin? Which amino acids in the proteins would contribute such groups?
What is the approximate rate of change of A340 measured? i.e. ΔA340 / min = __________ What rate of change of A340 would you predict if 30 ml of the ADH solution was tested in the same way (i.e. half the amount of protein) ? i.e. ΔA340 / min = __________ What rate of change of A340 would you predict if 60 ml of a 0.5 μM ADH solution was tested in the same way? i.e. ΔA340 / min = __________ As well as writing your answers, explain your reasoning.
Are triacylglycerols : insoluble in water? very oxidized, contain-glycerol-fatty acids and spingosine, or do they possess a -1charge at 7.0 pH? can you select the true statement?
Amino acids, such as glycine, are the key building blocks of proteins and will be discussed in greater detail in Chapter 25. At the pH of the stomach, glycine exists predominantly in a protonated form in which there are two acidic protons of interest. The pKa values for these protons are shown. Using this information, draw the form of glycine that will predominate at physiological pH of 7.4.

CYP2E1 has a much higher Km for ethanol than ADH (11 mM versus 0.05 mM,respectively). When greater portions of ethanol are ingested (0.08% or 17 mM), which part of the statement would be true?
A 0.0284 M aqueous solution of lactic acid, HC3H5O3, a substance that accumulates in the blood and muscles during physical activity, is found to be 6.7% ionized. Determine the value of Ka for lactic acid.
Given the following data, calculate Keq for the denaturation reaction of the protein β-lactoglobin at 25oC: ΔH° = –88 kJ/mol ΔS° = 0.3 kJ/mol. The free energy of hydrolysis of ATP in systems free of Mg2+ is −35.7 kJ/mol. When the concentration of this ion is 5 mM, ΔG°observed is approximately −31 kJ/mol at pH 7 and 38°C. Suggest a possible reason for this effect.
When a mixture of 3-phosphoglycerate and 2-phosphoglycerate is incubated at 25°C in the presence of the enzyme phosphoglycerate mutase (which catalyzes the intervconversion of the two substances) until equilibrium is reached, the final mixture contains 6 times as much 2-phosphoglycerate as 3-phosphoglycerate.
