- 9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.

- Sodium borohydride (NaBH4) is a potent inhibitor of aldolase. It is known to ONLY inhibit theenzyme when it is complexed with substrate. Treatment of the enzyme alone has no effect.What is the mechanism for this inhibition? Please draw out the mechanism and show how it inhibits this.arrow_forwardShow the fate of the proton on the 4-Oxygen molecule of F-1,6-BP.
