Shown below is the structure of the amino acid, tyrosine. Part A) 5 points How many acid-base equilibria do I have to consider in tyrosine? Use the table below to find out. Part B) 25 points The pKa values of tyrosine are 2.2, 9.11 and 10.07. Indicate what equilibria these pKa represent. Indicate the correct overall charge of each species.   Part C) 10 points Indicate quantitatively which equilibria can be neglected in your calculation of contributions to total tyrosine concentration.   Part D) 20 points Calculate the equilibrium concentrations of all molecular species present in a tyrosine solution at pH 9.5 that you obtained by mixing NaOH and tyrosine to give a solution that is 0.1 M in total concentration of this amino acid, tyrosine.   Please do not fill in anything in the box provided below but instead upload your written answer as per instructions.

Consider the peptide below, it is made up of 9 amino acids. The second amino acid, phenylalanine, has no ionizable groups that can engage in protonation/deprotonation equilibria in the pH range 0-14.

The Lennard Jones Potential as a function of distance combines attractive and repulsive terms which leads to a minimum energy at a distance ro between two gas molecules or two atoms in a molecule.

Many but not all gas molecules have 3 translational and 3 rotational degrees of freedom.

Ozempic is the brand-name for semaglutide (S), a glucagon-like peptide 1 (GLP-1) receptor (R) agonist used to improve glycemic control in type 2 diabetes mellitus, treat obesity, and reduce the risk of major adverse cardiovascular events. The dissociation constant of semaglutide binding to GLP-1 receptor has been reported to be in the range of 1 to 10 nM. The estimated number of receptors per cell is 10,000, corresponding to an approximate concentration of 10-8 M. After daily oral administration of 7 and 14 mg the blood concentrations of semaglutide were found to be 6.7 nmol/L and 14.6 nmol/L, respectively. After answering the questions A-C below, please fill out the following table: Dissociation constant Association constant

Shown below are five potential energy versus distance graphs for a gas, labeled A-E. Please answer the following questions: Part A) 10 points One of these graphs represents a gas model that is described by the following equation: p x (V-nb) = n R T Select which graph (use the letter labels) and explain your choice. Part B) 15 points Shown below is a table about the behavior of some gases. Table 1: van der Waals constants for some gases Substance molar mass, g a (L2-atm mole–2) b (L mol–1) hydrogen H2 2 0.244 0.0266 helium He 4 0.034 0.0237 methane CH4 16 2.25 0.0428 water H2O 18 5.46 0.0305 nitrogen N2 28 1.39 0.0391 carbon dioxide CO2 44 3.59 0.0427 carbon tetrachloride CCl4 154 20.4 0.1383 Using the equation from Part A, calculate the pressure of 25 L of 2 mols of CO2 gas at 298 K and compare it to the pressures you obtain with using the ideal gas and the van der Waals equations. Part C) 10 points Describe and offer a possible explanation for the differences you obtain in the pressures in Part B. Part D) 15 points Assume that the graphs A-E are for H2 gas. Sketch what you might expect the graphs to look like for CO2 gas in comparison to H2 gas (so 2 lines per graph, labeled “H2” and “CO2”, each).   Please do not fill in anything in the box provided below but instead upload your written answer as per instructions.
