The Lewis structure for the tripeptide tyrosine-histidine-glycine has to be drawn. Concept introduction: Amino acids condense to form peptide bonds releasing small water molecules. A peptide bond is the chemical bond which is formed between two molecules of amino acid when carboxyl group of one molecule reacts with the amino group of another molecule. A polypeptide containing n amino acids will have ( n − 1 ) peptide bonds. The side of a polypeptide chain having free carboxylic group is called C-terminal and the side having free amino group is called N-terminal end.

Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!! I am reposting this—ensure all parts of the question are straightforward and clear or please let another expert handle it thanks!!
