It is difficult to draw the entire structure of the peptide you have listed in your question. A peptide is formed when the carboxyl group (-COOH) of one amino acid combines with the amino group (-NH2) of a second amino acid.
General structure of a peptide bond: -C(=O)-NH-
A peptide is usually written from N-terminus to C-terminus.
In your question, first combine the carboxyl group (-COOH) of Lysine with the amino group (-NH2) of Tyrosine. Continue this process until you have combined all the amino acids. The general structure of your peptide should look like:
H2N - CH(R1) - CO - NH - CH(R2) - CO - NH - CH(R3) - CO - NH - CH(R4) - CO - NH - CH(R5) - COOH
Where R1 to R5 represents the side chain of each amino acid. Hope the above was helpful.
