Question Description
I need support with this Chemistry question so I can learn better.

This is a take home Final please be detailed and answer everything according to the word limit, thank you!!

The following questions are based on the topics we covered in class. I have provided the relevant manuscripts. However,I encourage you to refer to additional scientific literature to come up with possible answers. You may include scheme(s) and/or figure(s) to illustrate a particular point. Please follow the recommended word limits (including the figure captions). Note that for the purposes of any activity in this class, you are prohibited from posting these questions and accessing the information provided by contract cheating sites (examples include Chegg, Course Hero and many others). Also, note that your answers will be checked for plagiarism.

Question 1: In the class, we will discuss the receptor binding domain (RBD) of COVID-19. A recent research report from the Scripps Research Institute at La Jolla indicates that despite ~80% primary sequence similarity, a neutralizing antibody, CR3022, binds to RBD of SARS-CoV with a much higher affinity than to that of COVID-19 (Kd of ~1 and ~115 nM, respectively). Using the accompanying manuscript as a guide, Yuan et al., Science 2020 (Figs. 1-3), explain this dramatic difference in the binding affinity. (400 words; 25 points).

Question 2: Carbonic anhydrases (CAs), which catalyze the reversible hydration of carbon dioxide to form the bicarbonate anion, were the first Zn2+-dependent metalloenzymes to be characterized. A diverse range of compounds inhibit CAs – acetazolamide is one such compound. Using the accompanying review as a guide, Aoki and Kimura et al (Schemes. 11 and 23), explain the catalytic mechanism of CA and the inhibition mechanism of acetazolamide. (400 words; 25 points)

Question 3: The first-line therapy for the treatment of hypertension and related diseases is the administration of angiotensin-converting enzyme (ACE) inhibitors. Moexipril is a long- acting ACE inhibitor suitable for once- daily administration. Explain the pharmacokinetics of Moexipril. (400 words; 25 points)

Question 4: In the past few years, several orphan GPCRs, for which endogenous ligands have not yet been discovered, have been targeted for therapeutic purpose. Human GPR139 receptor is one such orphan GPCR. Using the accompanying review as a guide, Vedel et al., Basic & Clinical Pharmacology & Toxicology 2020, explain the following – 1) orphan GPCRs; 2) criteria used for “deorphanizing” a GPCR; 3) agonist pharmacophore model described in this review (Fig. 3); 4) proposed agonist binding site (Fig. 4).

Assignment: Medicinal Chemistry Essay

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality

Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes

I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
It is best to paraphrase content and cite your source.
LopesWrite Policy

For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy

The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
I do not accept assignments that are two or more weeks late unless we have worked out an extension.
As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication

Communication is so very important. There are multiple ways to communicate with me:
Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
