Case Study – Graduating from PHS Adapted from: http://sciencecases.lib.buffalo.edu/cs/ Instructions: · Read the case study below · Answer the questions in full sentences using your own words · Make sure to read each question carefully and thoroughly when structuring your answer Case Study: Keyson is at the end of his Pre-Health Science journey. He is proud of all he has accomplished and is looking forward to next steps. As Keyson is preparing to graduate, he has decided that a career in health care might not be for him. He has discovered instead that he has an interest in food and food science. Before he commits to a food science program, Keyson decides to look for a summer job working in a food lab. Keyson feels that an entry level job in a food lab will provide him with hands-on experience and exposure to the industry he is curious about becoming a part of. In preparation for job interviews, Keyson decides to brush up on some organic chemistry and biochemistry knowledge specifically around food. He hears a lot in the news about energy drinks and has become very health conscious since learning about biomolecules in his chemistry and biology classes. After some research, Keyson discovered this very helpful case study with detailed information on popular energy drinks: https://sciencecases.lib.buffalo.edu/files/energy_drinks.pdf. Specifically, Keyson was interested in the following information from the document: · calorie content of each drink · marketing claims · ingredients and nutrition facts Some ingredients were familiar to Keyson from his biology and chemistry studies but others almost sound like made-up words. Keyson decides to dig deeper to learn more… Application Questions 1. [10x0.5 = 5 marks] Using the information from the case study at https://sciencecases.lib.buffalo.edu/files/energy_drinks.pdf, categorize the biomolecules in the table below. Use 1 letter match for each biomolecule. [NOTE: The case study is also available as a PDF in the assignment folder if the link does not work]. A. source of energyC. stimulantE. artificial sweetenerG. metabolism B. amino acidD. vitaminF. preservative NOTE: Letters may be used more than once or not at all Biomolecule Letter match Biomolecule Letter match Sucrose Potassium sorbate Citric acid Fructose Taurine Caffeine Aspartame Sucralose Glutamine Folic acid 2. [3 marks] Find the chemical formulas for niacin and niacinamide using the case study provided. Record the formulas below. Are these ingredients isomers? Why or why not? Niacin Niacinamide Isomers? Comment. 3. [1 mark] Of all the ingredients on the biochemical information list, which surprises you the most? Why? Would you consume or avoid an energy drink with this ingredient? Why? Ingredient Comments Keyson decides to further his food science research by exploring fats and lipids. He knows some fats are healthy and some are not. He is keen to learn more. In his research Keyson comes across a fat called olestra. Olestra is a synthetic fat that was discovered, by accident, in the 1960's. In the 1990’s it became popular because it had the taste and texture of a real fat but did not cause weight gain. Keyson found the following links useful in his olestra research: · https://onlinelibrary.wiley.com/doi/pdf/10.1002/clc.4960190508 · https://en.wikipedia.org/wiki/Olestra · https://www.thecanadianencyclopedia.ca/en/article/olestra-controversy · https://recipes.howstuffworks.com/question526.htm 4. [1 mark] Research olestra using the links provided. In your own words, why was olestra banned? 5. [1 mark] A molecule of olestra is shown below. Which functional groups are indicated? A B A B 6. [2 marks] Using the links provided, how is the structure of olestra different from that of a normal fat/oil? Normal fat/oil Olestra “backbone” # of fatty acids attached to “backbone” 7. [1 mark] In your own words, how does olestra impact vitamin absorption? Keyson enjoys cooking and watching food shows and food documentaries. He has become a big fan of barbecuing. Keyson is getting ready for summer and checks the fuel level on the barbecue tank. Keyson enjoys a side of French fries with vinegar with his burgers. 8. [3 marks] Which organic compound is the fuel commonly used in barbecue tanks? Briefly describe the structure of this organic compound, including the type of functional group. Organic compound in BBQ tanks Structure Functional group 9. [3 marks] Draw the structural formula for vinegar. [You must draw this by hand by either using the “Draw” function in Word, or draw by hand, photograph and insert the image in the table]. Vinegar is also called “acetic acid” – what is the IUPAC name for vinegar and which functional group is present? Structural formula IUPAC name Functional group Keyson’s friend is also getting ready for job interviews. He just came over to study after getting his nails done and is complaining of a headache. They both look into what chemicals are used at the nail salon and find that acetone is commonly used. Could acetone be the explanation for Keyson’s friend’s headache?  10. [3 marks] Draw the structural formula for acetone. [You must draw this by hand by either using the “Draw” function in Word, or draw by hand, photograph and insert the image in the table]. What is the IUPAC name for acetone? Which functional group is present in acetone? Structural formula IUPAC name Functional group 11. [1 mark] What health risks are associated with acetone? Comment in 1-2 sentences and provide link(s) to any source(s) used. Link(s): 12. [1 mark] What is acetone used for in nail salons? If Keyson pursues a career in science, he will have to constantly update his knowledge and skills as new discoveries are made in chemistry all the time. Discoveries in new materials to make smartphones thinner and lighter, to discoveries in medicine to save lives. 13. Research to find 2 current news items/resources with a publication date from 2018 onwards. One item must relate to organic chemistry and one must relate to biomolecules. · [1 mark] If web based, provide a link to the resource. If text based, provide a reference for the article. · [1 mark] Provide the date the item was published/reviewed. · [2 marks] Summarize the item in 3-4 sentences. · [1 mark] Describe the connection between the item and a topic/learning objective covered in this course. NOTE: Items should be from reliable and reputable sources. Universities, governments, research institutes, advocacy groups/organizations (i.e. SickKids hospital, Canadian Cancer Society) and trustworthy news platforms are good options. Wikipedia, personal websites made by private citizens etc. are not typically considered reliable sources.
