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…
Isoelectric focusing can separate peptides based on their relative contents of acidic and basic residues. When voltage is applied to an electrophoretic gel with Amino acid pK Arg 12.5 a pH gradient, each peptide migrates until it reaches a point where it has no net charge. The pH at this point is the isoelectric point (pl) for that peptide. Asp 3.7 Cys 8.2 One can estimate the pl fairly accurately (within 0.1 or 0.2 pH units) using the Glu 4.3 pK values of all the proton dissociable groups in the peptide. His 6.0 Consider the hexapeptide Met-Asp-Lys-Arg-Ala-Tyr. Lys 10.5 Tyr 10.5 *peptide-NH; 8.0 *peptide-COOH 3.4 * Amino and carboxy terminal values differ from the a amino and carboxy values of a single amino acid. Step 1: Determine the total positive charge on the hexapeptide when all acidic and basic groups are fully charge: protonated. Enter your answer without the sign.
Could someone explain what this is saying? I would like a better understanding. FIGURE D CPP32 (Caspase-3) protease activity. Aliquots of cell lysates (50μL) were incubated with an equal volume (50 μL) of the reactionbuffer and 5 μL of 7-amino-4-trifluoromethyl coumarin (AFCDEVD) for 1 hour at 37˚C (Clontech). The shift in fluorescenceemission of AFC-DEVD, on its proteolysis to free AFC by theprotease, was detected in a fluorometer, using a 400 nm excitationfilter and 505 nm emission filter.

Enz-SH + Ag* - Enz-S-Ag + H* The affinity of Ag* for sulfhydryl groups is so great that Ag* can be used to titrate -SH groups quantitatively. To 10.0 mL of a solution containing 3.5 mg/mL of a pure enzyme, an investigator added just enough AGNO, to completely inactivate the enzyme. A total of 0.536 umol AGNO, was required. Calculate the minimum molecular weight (M,) of the enzyme. minimum M, = The determined M, is not exact, but it is a minimum value for the M, of the enzyme. Why does the M, value obtained this way give only the minimum molecular weight? There is only one polypeptide chain. There are no disulfide bonds in the protein. There is only one titratable -SH group per protein molecule. The Ag* would also react with the terminal carboxyl group.
