A scientist wishes to substitute an amino acid in an iron-transporting protein from that of a bulky, charged side group to that of a small, uncharged side group. what effect will this have on the function of the protein?

A change in the three dimensional structure of protein will result.

Explanation:

Proteins are biomolecules which remain in the folded state and have a shape in accordance with the sequence of amino acids in the polymer. The structure of the protein is related with the 3D structure of the protein.

Thus a change in the 3D structure of the protein is likely to change the effectiveness of the protein in the process of iron transporting. This can be said that the structure and function of protein are related.
