Predict the site of protonation and deprotonation for each of the following molecules. Explain your reasoning.
1. Use your own words or drawing to show the protonation and deprotonation of Lysine when PH increase from 1 to 11. 2. We know that the pKa of Histidine is 6.5. Explain what will happen at physiological pH. And it is the residue most frequently involved in enzymemediated catalysis. Explain why base on the known features of Histidine. You can use serine protease Trypsin as an example. These are my protein structure homework, pls help
Identify the products of the following reactions and propose a mechanism for its formation. Please explain each step i.e. protonation, deprotonation, loss of leaving group, or nucleophilic attack and describe what kind of reactions they are. Include BOTH major and minor products. Thank you in advance. NaOEt EtOH Me H0 2 CI 6 12 CI acetone NaOEt EtOH Me H0 2 CI 6 12 CI acetone
Based on these data, predict the site of action of the new compound. Explain your reasoning. Match the items in the left column to the appropriate blanks in the sentences on the right. Macías-Rubalcava et al., in J. Photochem. Photobiol. (2017) B 166:35-43, investigated the mechanism of action of several compounds that might serve as new herbicides. One of these new compounds (#7) inhibited photophosphorylation. The data below show the effects of compound 7 on uncoupled electron transport in isolated...
