Disulfide bonds are often found to stabilize which of the following levels of protein structure?

Identify the reagents for each step in a reaction series:      

The three long problems are available below.  Problem 1. (33 pts).  This question has multiple parts; please ensure you indicate the answer for each part.  Using the framing floor plan shown below for a 10-story building. Determine the following: a. Determine the tributary area for the typical interior beam. b. Determine the tributary area for the typical spandrel (or perimeter) beam.  c. Determine the tributary area for the typical interior girder.  d. Determine the tributary area for the typical spandrel (or perimeter) girder.  e. Determine the tributary area for the typical interior column. f. Determine the tributary area for the typical corner column. g. Assume each floor must support a dead load of 75 psf and a live load of 30 psf. Determine the required strength for the interior column that supports five levels as required by the LRFD design approach.     2.  Determine the maximum factored load that can be applied in tension to the angle shown below. The angle is ASTM A36, and it is connected with four 3/4-in. diameter bolts—neglecting block shear (33 pts).    3. The following problem consists of three parts: The W12 X 53 tension member shown below has two rows of three 1-in.-diameter bolts in each flange. Assuming A572 steel and considering the strength of the W12X53 only (34 pts),  a. Determine the design tension strength of the W12 X 53. b. Determine the service dead load that can be supported if there is no live load, and c. If a service dead load D=100 Kips is applied, what is the maximum live service load that can be supported?
