1. Look up the structure of naproxen on google image search. Draw the structure below and indicate the acidic proton by circling it. What would the conjugate base of naproxen look like? 2. On another sheet of paper, draw a mechanism for the protonation of... a. water b. methanol c. formaldehyde d. triethylamine 3. On another sheet of paper, draw the mechanism for the deprotonation of... a. methane b. the SH of cysteine C. ammonia d. the OH of butanoic...
Explain why graphite can be conductive and is a molecular solid based upon its structure and hybridization.
9. Look up and draw the ring structure of Lactose. Circle the glycosidic bonds. What type of saccharide is it considered?
a) which amino acid tested is most polar? b) look up the structure of the amino acids. explain why it makes sense that the amino acid you listed is more polar than the others? c) what amino acids are in the fruit juice? D. CHROMATOGRAPHY Chromatography is a general technique that is used to separate various materials. In this case, students can use the unique chemistry of the amino acid to determine its migration in a specific solvent. The solutions...
3: Hydrophobic patterns and structure. 3a: exploring a single helix Observe: Look up the Leu and Val sidechains in your book. Draw them below. Are they hydrophobic or hydrophilic? Explain. Observe: Draw a sketch of the peptide, including where you would expect to find H-bonds and the location of the hydrophobic amino acids. Predict: Do you think this structure is stable in aqueous solution? Why or why not? Examine the model you made for the pre-lab to help formulate your...
Post-Lab Questions 1. Look up the structure in your textbook of the amino acid you titrated. Write the structure you expect at pH (a) 2.5 and (b) 12 2. Compare your isoelectric point value (pl value) with the value of the amino acid listed in your textbook. How does it compare? Into which class does your amino acid fall? 3. Which data point can you obtain with greater accuracy from your graph-the pK values from the "legs" or the isoelectric...
Using the five-component model, explain the difference between IT and IS. Explain why you can buy IT, but you can never buy IS. What does that mean to you, as a potential future business manager?
1. Look up a three dimensional structure of hexaphenylbenzene. a) What are the orientation of the outside benzene rings with respect to the central benzene ring (dihedral angle)? b) Hexaphenylbenzene appears to have an extended conjugation system, and might be expected to be colored, however, the compound is white. Briefly explain this observation
Hashing can best be compared to the index of a book. You look up a key word or phrase, and the index gives you what page to look at. But when you get to the page, you may have to do a little more scanning until you actually find the word. A little work, but better than scanning from the start of the book to the end. So, for this discussion, in your own words, explain how hashing works when...
please draw neatly. Thank you! Look up the structures of uracil and thymine in the McMurry book. Draw them, and describe how they are different Look up the structures of homocysteine and methionine in the McMurry book. Draw them, and describe how they are different. Tetrahydrofolic acid is used to transfer methyl groups. Look up the structure of tetrahydrofolic acid and draw it. (A good source is PubMed] Look up the structure of folic acid [in PubMed] and describe how...
