1)Ubiquitin is a small protein with a monoisotopic mass of 8560 Da. a) Electrospray ionization of this small protein typically results in major charge states of +8, +9, +10, +11, +12, and +13.

c) Jean-François is studying a specific protein in a research laboratory. In previous experiments, he observed that this protein seems to function as a receptor protein on the surface of cells that recognizes a specific hormone involved in cell-cell communication. Jean-François prepares his final experiment, but makes a mistake in calculating how much HCl to add to one of his solutions to get the correct pH. He performs the experiment, and much to his surprise, he observes that his protein no longer seems to be recognizing the hormone anymore as he had observed in previous experiments. Propose a hypothesis that briefly explains (2-3 sentences) why the results of Jean-François’ experiment have changed. oportmost likely h beens dy the celyd must irst ir o nm cof the st omce MAnoncalest wanti patient Hewe umourcells Becnuse of falla anan intoindidual.cells. protein d) True or false: A mutation could cause the same change in Jean-François' experimental results as the change in pH described…

Mark as true or false the statements about amino acid reactivity and peptide synthesis: ( ) Peptides are very diverse in terms of their function/application. Some are hormones or their releasing factors, some are neurotransmitters, some are toxins, some are natural antibiotics, and some work as sweeteners, such as aspartame. ( ) Most of the natural peptides occur in low concentration, which makes their isolation from the matrix difficult, and therefore, their chemical synthesis is necessary. ( ) The chemical synthesis of peptides is only done with the use of enzymes ( ) A difficulty in the synthesis of peptides is due to the fact that carboxylic acids and primary or secondary amines do not form amide bonds easily. When mixing the two, what we would have would be products from the transfer of protons between them, forming a charged species. ( ) The chemical synthesis of peptides uses a chemical reagent to activate the carboxylic acid of the amino acid, which will undergo nucleophilic…
