QUESTION 9
Why are protecting groups necessary when generating polypeptides?
Amines and carboxylic acids are unreactive without the use of protecting groups.
Amino acids are multifuctional molecules and the reactivity needs to be limited to the amine and carboxylic acid that are to form the desired
amide bond.
Amino acids are too reactive and need to be modulated in the reactivity.
Protecting groups are unnecessary in polypeptide synthesis.
