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 arecoming from the alpha-helices in these proteins, and many alpha-helices have similar absorbance properties across different proteins, whichprotein 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 respectivewavelength of maximum absorbance, and record this information in your lab notebook (which you will submit online). Remember that molarabsorptivity is an intrinsic property of each protein, so you will get a single molar absorptivity for each of the three proteins. A 1 cm quartzcuvette was used for each protein, and the absorbance values below are reported for the wavelength of maximum absorbance for eachprotein. You should use Excel to assist you with this work, and you should include all three of your Excel plots in the lab notebook portion ofthis lab that you will be submitting online. HINT: Remember that we should add a point at (0,0) since we always remember to calibrate ourspectrometer with a blank!ProteinAbs. at c=0.11 MAbs. at c=0.36 MAbs. at c=0.76 M0.060.150.33Glycoprotein0.440.931.45Protease1.152.140.53RNA binding proteinNow that you have these molar absorptivity values, let's look at some samples from people who would like to get tested using the method wehave developed. We need to determine the concentration of SARS-Co\V-2 proteins given the following information for several patients thathave tested positive in other types of COVID-19 tests.Patient 1: Upon examining for protease protein, it was found that the sample has an absorbance of 1.22 absorbance units in a 2 cm cuvette.Patient 2: Upon examining for glycoprotein, it was found that the sample has an absorbance of 0.072 absorbance units in a 0.1 cm cuvette.Patient 3: Upon examining for RNA binding protein, it was found that the sample has an absorbance of 1.45 absorbance units in a 0.5 cmPlease summarize your results for these patients in your summary report. Also address what you might see as potential benefits or problemsn natient hlond, Do you think we could examine a blood sample directly using thiscuvette.

First question had been answered. Absorbance of a solution can be calculated using Beer Lambert law.

Conclusion 5: You are tasked with analyzing a suspiciously pink sample of drinking water to establish if it has unsavory levels of MnO4-contamination.
