Answer
The resultant protein would likely have a structure that is highly influenced by hydrophobic interactions, leading to a compact, globular form with hydrophobic residues predominantly buried in the interior.
Solution
a
Hydrophobic Core: The hydrophobic residues will tend to cluster together to avoid contact with water, forming a hydrophobic core. This minimizes the exposure of hydrophobic side chains to the aqueous environment
b
Tertiary Structure: The protein will likely fold into a compact, globular shape where the hydrophobic residues are sequestered inside, and hydrophilic residues are exposed on the surface
Key Concept
Hydrophobic interactions drive protein folding
Explanation
Hydrophobic residues in a polypeptide will drive the folding process to minimize their exposure to water, resulting in a compact, stable structure with a hydrophobic core.
