macollege.instructure.com/courses/352/pages/covid-proteins-lab-manual?module_item_id=D44333 A = abc Where "A" is absorbance, "a" is molar absorptivity, "b" is the path length (length of the cuvette in units of cm), and "c" is concentration (mol/L). 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…
