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?
Homework Answers
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.

Carboxylic acid functional group and Functional amine group
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...
