Under standard conditions, the binding free energy for a ligand-protein complex,

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.

How much heat is required for the isobaric expansion of 10 liters of nitrogen gas when going from 25oC to 25 liters at a pressure of 1 bar? You can assume ideal gas behavior.

Fourier’s law states that the conductive heat transfer rate across a solid surface is

According to learning curve theory, there is a constant rate that applies to a given repetitive  task. If the task time T1= 12 hours and the learning rate 78%. Calculate T8

A basic process map includes arrows to indicate

Jasmin is precious for the production of parfumes. In Egypt workers are underpaid doing the job of harvesting Jasmin and due to poverty a lot children hat to work on the fields. Mark all correct!

In the United States, 40% of the population have brown eyes. If 15 people are selected, find the probability that at least 10 of them have brown eyes.  Is 10 a significantly high number of people with brown eyes in a group of 15 people?

Suppose that pulse rates among healthy adults are normally distributed with a mean of 79 beats/second and a standard deviation of 10 beats/second. Draw the bell-shaped curve, label it, and shade the portion of the curve that corresponds to the probability in question. What percentage of healthy adults have pulse rates that are more than 75 beats/minutes?
