The ecological consequences of chronic malathion application to cotton fields needs to be explained. Concept Introduction : Within the chemical family, malathion is recognized as organophosphates. It is an insecticide. Products which contain malathion are utilized outside to regulate the broad range of insects within agriculture and homes.

Question

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. (5 pts—this will be scaled up appropriately if your gel did not develop properly) dye MW Whey Peak 1 Peak 2

what are the different classes and some examples of neuroprotectants that can be used to treat, prevent, or combat neurotoxicity/a neurotoxicant...for example, antioxidants, nutraceuticals, etc.,..?

Imagine that aldolase can react with the seven carbon molecule Sedoheptulose-1,7-bisphosphate (below). Use the mechanism to predict the two products generated. Please draw out the stereochemistry in a fischer projection.
