Be sure ロ.口 olaAll amino acids have two ionizable functional groups: an α‑amino group (average p?a of 9.4) and an α‑carboxylic acid group (average p?a of 2.2). Aspartic acid has an ionizable side chain (R group) with a p?a of about 3.8. One of the possible ionization states of aspartic acid is shown in the image. The protonated form of the R group of aspartic acid is shown in the structure. The ratio of the protonated form to the charged (deprotonated) form depends on the p?a of the R group and the pH of the solution. Select all the pH values at which the charged form of the R group would predominate.

The molar absorptivity is an intrinsic property of a molecule which tells us how intensely it will absorb at a particular wavelength. If "A" is a unitless quantity, "b" is in units of cm, and "c" is in units of mol/L, then what are the units of molar absorptivity? Do a little research to learn how alpha-helices and beta-sheets are drawn in protein structures. If most of the absorption properties are coming from the alpha-helices in these proteins, and many alpha-helices have similar absorbance properties across different proteins, which protein would you predict would have the highest molar absorptivity? Your job is to use the following data table to determine the molar absorptivity for each of the following proteins at their respective…
