Below are the molecules for epinepherine and ceramide. In the blanks below, identify all stereoisomers, these can include chiral centers and geometric isomers. For molecules with more than one stereoisomer, separate all identified groups with a comma in the blank Epinephrine [epi] Ceramide [cer]

You have developed a small molecule antiviral that shows promise against the flu. Before you can move forward with your new drug, you need to test for any off target affects. You immobilize your small molecule on resin beads, incubate them in a tissue lysate, and then rinse away the beads. Any host proteins that bind your drug will remain with the beads. After numerous rinses, the drug is released from the beads, and the released product is run on an isoelectric focusing gel. Afterwards, the gel is run on an SDS-PAGE gel. Based on the gel below, estimate the isoelectric point and the molecular weight of the bound protein.    Isoelectric point: [pI] Molecular weight [MW]

From the following titration curve, identify the species at each of the designated points on the graph from the available structures 1. [AA1] 2. [AA2] 3. [AA3] 4. [AA4]

Photoelectric interaction with an atom is much more likely to occur with:

The code below displays a result for a score of 85. Which option converts it into a user-defined function named grade that takes the score as a parameter and returns the result, and then displays the result for a score of 85? score = 85if score >= 70:    print(“Pass”)elif score >= 80:    print(“Merit”)else:    print(“Review”)

A 35 keV x-ray will most likely undergo K-shell photoelectric interaction with which of the following?

Which of the following conditions are diagnostic x-rays most likely to be performed under?

The technical factors for a hand x-ray were set at 4 mAs and 55 kVp. A repeat image was taken at 2.5 mAs and 65 kVp. Would you expect the differential absorption to be higher or lower in the second image?

After a Compton interaction with an outer shell electron of a calcium atom (BE = 0.04), the recoil electron sped away with 10 keV of energy. The scattered photon was deflected at an angle of 75 degrees from the original photon retaining 62 keV of energy. What was the energy of the incident photon?

The RBE (Wr) of diagnostic x-rays is equal to ________.
