How was thermal stability measured in this paper and describe how GRL-1720 and 5h affect the thermal stability of Mpro and which drug has the larger effect? https://www.nature.com/articles/s41467-021-20900-6
Data from enzyme inhibition are used to determine a Kmapp and Vmax PP. Comparison of these values with assays run without inhibitor are used to understand how the inhibition is occurring. This is useful for better understanding the active site as well as the practical aspect of pharmaceutical drugs. Below are idealized Line-Weaver Burke plots of different types of inhibitors. Comnetitive Uncomnetitive Mixed +Inh +Inh 4Inh Anh Inh Anh [S] [S] [S] a. How does the value of Vmax for the enzyme compare to the Vmax PP of the inhibited enzyme for: i. Competitive ii. Uncompetitive iii. Mixed b. How does the value of Km for the enzyme compare to the Km PP of the inhibited enzyme for: i. Competitive ii. Uncompetitive iii. Mixed c. For each situation in Model 1, consider an inhibitor that is better than the one shown on the graph. Answer the following questions for each type of inhibition: i. How would the KmPP change? ii. How would the Vmax PP change?

The Commercial Trainee Program of the Pharma Biotec Industry, opened selection to admit candidates who would help in the development of a more efficient production protocol of Ibuprofen, a non-colloidal anti-inflammatory. Basically, the challenge stimulated obtaining high enantiomeric purity of the final product. In this way, the candidates proposed the use of immobilized enzymes for the process. Tick the most coherent alternative to justify the choice of using immobilized enzymes by the candidates for the case mentioned above in the question. (Only one statement is true)* A)The use of immobilized enzymes was an interesting strategy, since different immobilization techniques can be used, such as adsorption and covalent. b) The use of immobilized enzymes was consistent since the immobilization process can further favor the regioselectivity , enantioselectivity and stereoselectivity properties of the enzymes, which will favor the enantiomeric purity of the drug. c) The use of…
