Beta-sheets are roughly planar structures, in which the backbone hydrogen bonding pattern defines the plane. Where are the side chains in a sheet? Select one: a. The side-chains are on the outside of the sheet. b. The side-chains are in the plane of the sheet, with residues from one chain on one side of the sheet, and residues from the other chain being on the other side. The side-chains do not have a consistent pattern. O d. The side-chains are perpendicular to the plane of the sheet, with residues from one chain being above and residues from the other being below the plane of the sheet. C. O e. The side-chains are perpendicular to the plane of the sheet, with residues from each chain alternating between above and below the plane of the sheet. O f. The side-chains are in the plane of the sheet, with residues from each chain alternating being on one side o the other of the sheet. g. Beta-sheets are rarely observed in proteins.

Question
Beta-sheets are roughly planar structures, in which the backbone hydrogen bonding pattern defines the plane.
Where are the side chains in a sheet?
Select one:
a. The side-chains are on the outside of the sheet.
O b. The side-chains are in the plane of the sheet, with residues from one chain on one side of the sheet, and
residues from the other chain being on the other side.
The side-chains do not have a consistent pattern.
d. The side-chains are perpendicular to the plane of the sheet, with residues from one chain being above and
residues from the other being below the plane of the sheet.
C.
e.
The side-chains are perpendicular to the plane of the sheet, with residues from each chain alternating
between above and below the plane of the sheet.
O f.
The side-chains are in the plane of the sheet, with residues from each chain alternating being on one side or
the other of the sheet.
g. Beta-sheets are rarely observed in proteins.
