Text (no question) allows instructors to give information about a part of the test.  Really, it could say anything, but usually I see it as giving instructions to use certain information for certain questions.   The following 5 questions will be about Unicorns.

Below are postulated protonation states of histidine. pKa values for histidine are 1.8 (a-COOH), 9.2 (a-NH3+), 6.0 (R group). Blank #1: List the letters of the 4 states that do NOT form at any pH, separated by commas.  Blank #2: List the letter of the zwitterion.  For blanks #3 -> #6:  For each of the 4 states that do form (the four you did not list in Blank #1) list the following: the letter of that state, and the approximate pH range in which that state predominates (>90%). Make sure to only do one state per blank. Separate the letter and pH with a comma (for example: B, 3.3 to 5.3 or B,

Fill in the Blank are questions where students have to know the answer and are not given choices to spark their memory.  Instructors have to include all acceptable answers and variations on answers on separate “Possible Answer” lines for Canvas to properly auto-grade.   Traditionally, unicorns have a single ___ emerging from their foreheads.

Below are the structures of two complex lipids (A and B). Three carbons are labeled in red in each molecule (C-1, C-2, C-3). Use these labels to answer your questions.  For blanks 1 -> 4, describe the differences between lipids A and B by making a statement like this: Lipid A has a ____________________, lipid B has a ___________________. Blank #1: polar head attached to C-1 (list all the molecule(s) that make the polar head for each lipid) Blank #2: bond at C-2 Blank #3: name of fatty acid attached at C-2 using delta nomenclature Blank #4: backbone of this molecule that includes carbons 1, 2, and 3 Blank #5: which of the two is likely found in more dense tissue (A or B)? Why?
