Answer;
-On the polar end or the hydrophillic end of the protein.
Explanation;
-Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups.The R group is often referred to as the amino acid side chain.
-Side chains which have various functional groups such as acids, amides, alcohols, and Amines will impart a more polar character to the amino acid. Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine.
Therefore; serine being a polar or hydrophillic amino acid will be found on the polar side chain of the protein.
Please continue the question. Or is that it?
I think it is D
Hope my answer help you?
