Please help me with the following question. Please explain.

3) The figure below shows the structure of a complex between peptide Y (colored in yellow) and protein M(colored in magenta). The dashed lines represent hydrogen bonds between some key side chains. Use thefigure to answer the following questions: a) What is the amino acid sequence of the peptide Y, beginning at its N-terminal end? Use the 3-Ietternaming code for amino acids. b) What secondary structure, if any, does Y adopt? Justify your answer with an observation from thefigure.
