Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

A recent article reported on the development of a new type of opioid drug that binds to a specific protein, but may not have the deleterious side-effects of many opioid drugs currently in use. The new drug is: N- N. The drug binds relatively tightly to the protein at low pH (Kd = 2 nM at pH = 5.5). The drug binds less tightly to the protein at higher pH (Kd = 18 nM at pH 7.4). Consider the drug-binding site in the protein. Explain briefly what aspect of the structure of the binding site could account for this result.

Phenolphthalein has a pKa of 9.7. It is colorless in its acid form and pink in its basic form. For pH=2.2, calculate [In−]/[HIn]. For pH= 4.8, calculate [In−]/[HIn]. For pH= 7.7, calculate [In−]/[HIn]. For pH= 11.4, calculate [In−]/[HIn].

All amino acids have two ionizable functional groups: an α‑amino group (average p?a of 9.4) and an α‑carboxylic acid group (average p?a of 2.2). Aspartic acid has an ionizable side chain (R group) with a p?a of about 3.8. One of the possible ionization states of aspartic acid is shown in the image. The protonated form of the R group of aspartic acid is shown in the structure. The ratio of the protonated form to the charged (deprotonated) form depends on the p?a of the R group and the pH of the solution. Select all the pH values at which the charged form of the R group would predominate.
