Why is His a particularly useful and highly versatile amino acid residue in enzymatic reaction mechanisms? To help compose your answer, consider the pKa of His and its role in both chymotrypsin and carbonic anhydrase catalysis
Homework Answers
Solution:
Histidine is considred as an important amino acids in enzymatic reactions due to its nearly neutral isoelectric point (pI) value of 7.59. It has three pka values (1.82, 6.00 and 9.17) It contains an imidazole side chain which is partially protonated and hence considered as positively charged amino acid at physiological pH. The histidine is a precursor for histamine, an amine produced in the body necessary for inflammation.
In chymotrypsin, histidine forms a cyclic triad gogather with serine and aspartate.
Histidine works as an activatator in the carbonic anhydrase catalytic reaction.

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
