3.An example of an amino acid is shown below. Answer the following questions ing to its structure.(1+1+1+1+2)
NH2
NH3
a. Circle the amine functional group. Is the amine neutral or ionie?
b. What is the definition of a zwitterion? Does this particular amino acid fit the definition?
c. Box the entire side chain of the amino acid. Use this to identify the name of this amino
acid.
d. Describe the character of the side chain. Is it nonpolar, polar, acidic, or busic?
e. Sketch the amino acid and what it would look like if you raised the pH up to 11. Is it
positively charged, negatively charged or neutral overall? Repeat this with the pH changed
down to 4.​
