Answer:
bacteria go through fermentation process and produce proinsulin then connecting sequence between A and B chain spliced an enzyme and the resulting insulin is purified
Answer:
the water is displaced weighed more than the boat
- During the chymotrypsin reaction, both the protonated and unprotonated forms of histidine 57 occur.
- This is possible within the physiological pH range thanks to its pKa of 6.0.
<h3>Describe the role that histidine 57 plays in the chymotrypsin mechanism.</h3>
- General base catalysis and general acid catalysis are two of the processes that histidine accomplishes.
- As a general base, it takes a hydrogen from serine 195 in the first step.
- The amide group of the peptide bond that is breaking is given hydrogen in the next phase, which is an acid catalysis step.
- The second stage of the reaction is conducted according to a similar plan.
<h3>Role of nucleophilic catalysis in the chymotrypsin reaction mechanism:</h3>
- The nucleophile that attacks the substrate peptide bond in the first phase of the reaction is serine hydroxyl.
- Water is the nucleophile that attacks the intermediate acyl-enzyme in the second step.
