Textbook Question
Chapter 27, Problem 37P
a. Draw the structure of the tripeptide A–A–A, and label the two ionizable
b. What is the predominant form of A–A–A at
c. The pKa values for the two ionizable functional groups (3.39 and 8.03) differ considerably from the pKa values of alanine (2.35 and 9.87; see Table 29.1). Account for the observed pKa differences.

At 0oC and 1 atm, the viscosity of hydrogen (gas) is 8.55x10-5 P. Calculate the viscosity of a gas, if possible, consisting of deuterium. Assume that the molecular sizes are equal.
Indicate the correct option for the velocity distribution function of gas molecules:a) its velocity cannot be measured in any other way due to the small size of the gas moleculesb) it is only used to describe the velocity of particles if their density is very high.c) it describes the probability that a gas particle has a velocity in a given interval of velocitiesd) it describes other magnitudes, such as pressure, energy, etc., but not the velocity of the molecules
