Chemistry discussion

Chemistry discussion. Rate of chemical reactions define how fast or how slow compounds form, this is an important factor when it comes to food industry. In order to increase shelf life of consumables, it is required to slow down decompositions reactions. In many cases, these reactions can be related to reaction with oxygen (oxidation). Sulfites and nitrites are inorganic compounds used as preservative or antioxidant. In this topic, you will extend your knowledge in scientific literacy by investigating recent research reports related to the use of either nitrites or sulfites.
Part 1
Go to Google scholar and search about sulfites or nitrites using the following expressions:
Sulfites nitrites
Sulfite good or bad
Nitrites good or bad
Sulfites and microbiome
Nitrites microbiome
Adverse health effects of sulfites (or nitrites) additives
Chose an article of interest, summarize the main topic of the research article and explain what health effects are highlighted in the article. Also, in your post, include answers to the following questions:
What are the names and chemical structures of the sulfites or nitrites additives used in food. What type of chemicals are sulfites?
Explain why sulfites or nitrites are added to food?
What would happen if sulfites or nitrites were not added to food?
Which sulfites or nitrites are naturally occurring compounds? Are they safer?
How safe is it for kids to eat food with sulfites?
Part 2
Answer the following questions:
How do you interpret the following expression: Sulfites are to wine as gluten is to food?
What type of sulfite are added to wine?
APA Citations: For each source you reference please use APA citation format.

Thin-layer-chromatography and the role of acid/bases (protonation deprotonation)

Thin-layer-chromatography and the role of acid/bases (protonation deprotonation). Protonated/Deprotonated Drug – General Understanding
I have a general problem in my understanding of protonated and deprotonated drugs and the role of pka.
Generally, a low pka indicted a strong acid.
When pka = pH we can expect to have a drug 50% protonated and 50% deprotonated.
However, when we go two unites above or below the pka value of a drug, then we can expect 99% of it to be undissociated and 1% dissociated.
For an acid it would imply that if: pH the protonated form exists predominately
When we have pH > pKa -> the deprotonated form dominates.
This now where I struggle when I try to apply these principles in practice.
From what pka range can I start classyfing drugs into “Basic” and acidic? Is a pka 10 and above considered a basic drug?
Lets take Paracetamol as an example. It has a pka value of 9,4, which I would interpret as weakly acidic.
– If I would add the paracetamol to an acidic environment, I would expect it to stay as it is with the OH. If I were to put it in a basic environment the OH would become deprotonated and instead of it there would be a negatively charged O-.
o But couldn’t at the same time the nitrogen become protonated from the acidic environment? Any why?
o ->How can I know which part becomes protonated or deprotonated?
What about nicotinamide? It has a pka of 3,3: Would it imply a deprotonation of NH2 in basic environments?
Also when looking at structures such as coffein. Is there any advice to quickly recognize the most basic nitrogen, which is most likely to become protonated?
Thin-layer-Chromatography Questions Worksheet A
Question 1:
You have paracetamol, coffein and acetylsalicylic acid. You want to perform 3 TLC with the different eluents.
TLC A: Ethyl acetate
TLC B: Ethyl acetate and formic acid
TLC C: Ethyl acetate and ammonia
Write the order of elution which you would expect for each TLC and explain your reasoning.
Question 2a) You have paracetamol, salicylamide, salicylic acid given. Write the order of elution for each TLC. Provide an explanation for each order.
TLC A: Ethyl acetate
TLC B: Ethyl acetate and acid
TLC C: Ethyl acetate and base
2b) In addition to the substances above, you now need to also analyse naphazoline nitrate. Is it possible to run a TLC with all these 4 substances together? Explain.
Question 3) How do you undergo analysis/detection in TLC? Explain the significance of the 254nm and 365nm values.

To prepare for this assignment, I recommend that you do the following:

Read these directions carefully.
Review the sample outline provided to you below.
Message me using Classroom Support with any questions!
Be sure to add your name and course number to your outline.

The outline format: Your outline must be formatted as described and exemplified in the example attached. Please note that this format will be assessed in your grade:

Use an alphanumeric sequence
Sections should be indented and aligned
Follow the suggested order of the required elements
Use brief but detailed and descriiptive phrases.
The required elements: Depending on the type of molecule/substance you have chosen you will address different sets of questions. Please see the category that responds to your selection. Your outline should contain the following elements in this order, and please note that some of these should be your personal observations. Also remember that your presentation (Assignment #3) should only be 10-15 slides, so you need to be concise and clear with your information.

Introduction

Molecule/substance Introduction
The common and IUPAC name of your molecule/substance. Please see this link to help with scientific names if needed: IUPAC Nomenclature Of Organic Chemistry: https://www.acdlabs.com/iupac/nomenclature/
Where you can observe your molecule/substance in society and/or in nature.
A brief discussion on why you chose your molecule/substance.
If possible, a picture and/or video of you safely observing your molecule/substance in the field. If you cannot safely observe it, please include a couple of images from the internet.
Body

Descriiption
You must include a physical descriiption. You can use your personal observations from photographs. If you cannot safely observe your molecule/substance, you must research.
Physical Characteristics (appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, etc.)
Chemical descriiption: You will need to research the chemical properties of your compound/molecule)
Chemical Characteristics (stability in air or other environment, flammability, volatility, etc)
Discovery
a. Describe the initial discovery of your molecule. Who discovered the molecule, when, how, etc? Some compounds are part of a larger substance/plant. If this is the case, describe the isolation of your specific compound. The isolation refers to the initial time your molecule/substance was discovered from its raw materials, or isolated from its natural resources.
Usage and Benefit or Harm to Society
Where has your molecule/substance been used. Is it used regularly or is has it only been used on occasion? If your compound is one we ingest when eating, include information on foods it’s commonly found in.
Write about the Benefit or Harm to Society Caused by your molecule/substance. Many compounds can be used as bioweapons or have both positive and negative impacts. Other compounds have had benefits as medicines or have caused harm as illicit narcotics. All of these are good ideas to start out thinking about, so I’d like you to discuss these impacts on society, the future, and in any way you can think they may be beneficial or harmful. Please see here for some hints on drug development.
Conclusion

This section should contain four to six points that sum up the main points from the body of the outline.
Start your conclusive section with one sentence summarizing some basic information about your chosen molecule/substance (common and IUPAC name and physical characteristics).
Continue with a brief summary (1-2 sentences) about the isolation and synthesis of the molecule/substance.
Include a brief summary (1-2 sentences) about the structure and function of your chosen molecule/substance.
Wrap up the conclusive section with a closing note that provides brief information about a unique fact and/or behavior of your chosen.
The Reference Section

This is not just the reference page; rather, referencing should occur throughout the outline as it will in your presentation. Therefore, your outline should include both a separate reference page containing a minimum of five sources listed in proper APA reference list format AND internal citations throughout the outline where appropriate. Please be sure to see the resources below for assistance regarding in-text citations and reference list formatting, and/or ask me if you have any additional questions.
