The structures оf fоur аminо аcids аre shown below and labeled 1–4. Using amino acids 1, 2, 3, and 4 in exactly that order, draw the structure of the tetrapeptide formed when they are joined by peptide bonds. Clearly show the N-terminus, C-terminus, all peptide bonds, and the R groups of all four amino acids. Show your work on Part II of the exam.
