Cleavage of the given cyclopeptide by trypsin and chymotrypsin gives the same fragments or not need to be identified. Concept introduction: Enzymatic cleavage is a useful method for identifying the sequence of amino acid residue in a large peptide. This method uses enzymes for hydrolysis of the peptide bonds. These enzymes are known as peptidases. Some of the frequently used enzyme is trypsin and chymotrypsin. Trypsin selectively hydrolyzes the peptide bond at the carboxyl side of arginine and lysine. Chymotrypsin selectively hydrolyzes the peptide bond at the carboxyl end of amino acids containing aromatic side chains. The amino acids which have aromatic side chains are phenylalanine, tyrosine and tryptophan. To explain : To explain whether the fragments obtained by hydrolysis of cyclopeptide using trypsin and chymotrypsin are same or different.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
