Where would you expect to find serine and alanine amino acids in a globular protein in aqueous solution?

1. Serine would be in the interior, and alanine would be on the exterior of the globular protein.

2. Alanine would be in the interior, and serine would be on the exterior of the globular protein.

3. Both serine and alanine would be in the interior of the globular protein.

4. Both serine and alanine would be on the exterior of the globular protein.
