Which statements correctly describe the probable locations of the amino acids? Asp is located on the external surface of the protein because it is charged. Ala is located on the external surface of the protein because it is polar. Thr is polar and can be located on the external surface or in the interior of the protein. Ile and Lys are located in the interior of the protein because they are not polar. Gln is located in the interior of the protein because it is uncharged.

Suppose that the sequence is part of a larger globular protein.
Consider the probable location, either on the external surface
or the interior of the protein, of each of the amino
acid residues.
The table gives the hydropathy index values for selected
amino acids in the peptide.
Amino acid
Hydropathy index
alanine
1.8
isoleucine
4.5
threonine
-0.7
glutamine
-3.5
lysine
-3.9
aspartate
-3.5
