The side chain (r group) of the amino acid serine is ch₂oh. the side chain of the amino acid leucine is ch₂ch(ch₃)₂. where would you expect to find these amino acids in a globular protein in aqueous solution? a) both serine and alanine would be in the interior and on the exterior of the globular protein. b) alanine would be in the interior, and serine would be on the exterior of the globular protein. c) serine would be in the interior, and alanine would be on the exterior of the globular protein. d) both serine and alanine would be in the interior of the globular protein. e) both serine and alanine would be on the exterior of the globular protein.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
