The apparent contradiction of the fact that more Benzedrine is required than Dexedrine to yield the same physiological response. Introduction: A carbon which has all the four different atoms or group of atoms has a tetrahedral geometry and such carbon molecule is referred as the chiral carbon. The two different forms in which a single chiral center can exist is referred as enantiomers. The narcolepsy and other related disorders are treated by amphetamine enantiomer (Dextroamphetamine). This medication is used because it is a potent central nervous system stimulant. The medications like Benzedrine and Dexedrine are similar in structure, but their physiological effects are different.

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.

Summary Introduction

To determine: The apparent contradiction of the fact that more Benzedrine is required than Dexedrine to yield the same physiological response.

Introduction:

A carbon which has all the four different atoms or group of atoms has a tetrahedral geometry and such carbon molecule is referred as the chiral carbon. The two different forms in which a single chiral center can exist is referred as enantiomers.

The narcolepsy and other related disorders are treated by amphetamine enantiomer (Dextroamphetamine). This medication is used because it is a potent central nervous system stimulant. The medications like Benzedrine and Dexedrine are similar in structure, but their physiological effects are different.

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.
