If Ca2+Ca2+ is often bound on the surface of a protein by carboxylic acid functional groups. If the pKa of a particular −COOH−COOH group is 4.4, would you predict Ca2+Ca2+ to be most tightly bound at pHpH 7, pHpH 4.4, or pHpH 3?
At pH =7
For binding of an ion to the acid it must exist in deprotonated form. mostly deprotonated form exist at ph=7, therefore calcium will be tightly bound at ph=7 because almost whole the salt will be deprotonated.

One of the problems with excellent data in vitro is that it is not always guaranteed to be equivalent to data in vivo. Therefore, it is important that what gives in vitro problems are resolved before getting the drug into in vivo studies to give it a better chance. For the following problems, how would you address each of the following for a target in the ER (CFTR)?1. If the drug is a small molecule with a carboxylic acid functional group...

the two carboxylic acid groups of aspartic acid have different acidities with pKa values of 2.1 and 3.9. Predict which acid group is the more acidic by considering the effect of the -nh3+ group on the stability of the conjugate bases. Explain your reasoning.
2. Explain why broad absorbances are expected for compounds containing alcohol and carboxylic acid functional groups. Draw the hydrogen bonding interaction between two ethanol molecules. 3. Draw a compound with a sterically hindered alcohol functional group. What is the most important and distinctive absorbance expected when assessing an IR of this compound? 5. Can IR spectroscopy easily be used to determine the structure of a molecule? Why or why not?
Maleic acid contains two carboxylic acid groups, one with a pka of 2.0 and a second with a pKa of 4.0. The fully protonated from of malice acid is shown on below. Briefly describe how you would prepare 0.25L of a 0.1 M buffer at pH = 2.0, assuming that you are starting with the disodium salt of the acid.
