Consider the following amino acids: Glutamine, Valine, Arginine, and
Glutamate.
For each scenario, state which amino acid is most likely to be found
and why (no more than 1 sentence each):
a. Contained within the phospholipid bilayer of a cell.
b. Involved in the deprotonation of Histidine.
c. In the exposed region of an extracellular receptor.
d. Electrostatically interacting with the phosphate backbone of DNA.
Your Answer:
A) Valine because it is nonpolar so it is hydrophobic
b) Arginine because it is acidic and it will accept a proton from histidine
c) glutamate because it is acidic and is often used as a recptor
d) Glutamine because it is polar and does Hydrogen bonding
3b, 3c, and 3d is amino acid incorrect 3c and 3d reasoning
incorrect
