Proteins have primary structure. If you are given a method to know which amino acid is at either of the two termini (ends) of a protein, can you connect this information to purity or homogeneity of a protein? | NCERT solution | Class 11 Biology | Unit-9 Biomolecules



Q.5:- Proteins have primary structure. If you are given a method to know which amino acid is at either of the two termini (ends) of a protein, can you connect this information to purity or homogeneity of a protein?

 

Answer:



If the same amino acid is present at both ends of protein, then it is a homopolymer. The protein is not pure in that case. On the other hand, a heteropolymer is a pure protein.
