Question

 A new drug is developed which selectively cleaves covalent
bonds between two sulfur atoms of non-adjacent amino acids
in a polypeptide chain. Which level of protein structure in
affected molecules would be most directly affected by the
drug

Answer 1

Albumin is a large protein which circulates freely in human plasma. Another
type of protein, called aquaporins, act as a channel for water to enter and exit a
cell, and are located within the lipid bilayer of a cell’s plasma membrane. Based
on their physiological locations, how would the tertiary structure of these two
proteins mostly likely compare?
a. Albumin has more of nonpolar core with nonpolar out layer while
aquaporins have a more polar core with polar outer layer.
b. Albumin has more of nonpolar core with polar outer later while
aquaporins have more polar core with nonpolar outer layer.
c. Albumin has more polar core with non polar outer layer while
aquaporins have a more of non polar core with polar outer layer
d. Albumin has more polar core with polar outer layer while aquaporins
have a more of non polar core with non polar outer layer
