In clinical pharmaceutical chemistry the aim is to understand biological transformations and processes associated with chemical entities inside the human body, and how those processes can be influenced with changes in chemical structures.
A well written multiple-choice question avoids obviously wrong or implausible distractors (such as the non-Indian city of Detroit being included in the third example), so that the question makes sense when read with each of the distractors as well as with the correct answer. A more difficult and well-written multiple choice question is as follows:
The 'rule of thumb' that the rate of chemical reactions doubles for every 10 °C temperature rise is a common misconception. This may have been generalized from the special case of biological systems, where the α (temperature coefficient) is often between 1.5 and 2.5. The kinetics of rapid reactions can be studied with the temperature jump method.
[100] [101] He is involved in clinical trials which apply the use of inhaled nitric oxide as a treatment for COVID-19. [102] This approach was inspired by the work of associate professor of emergency medicine at the Harvard Medical School N.

Measuring the concentration of various molecules can be useful for many applications, such as determining the therapeutic index of a drug candidate in a clinical trial. [2] To obtain serum, a blood sample is allowed to clot (coagulation). The sample is then centrifuged to remove the clot and blood cells, and the resulting liquid supernatant is ...
