The polypeptide Tyr-Gly-His-Phe-Val has to be numbered. Concept Introduction: Polypeptides are the ones that contain about 40 − 50 amino acids in a chain. Amino acid units that is present in the polypeptides are known as amino acid residue. In a linear polypeptide, the end of the chain that has free amino group is known as N-terminal while the end that has free carboxyl group is known as C-terminal. Numbering of the polypeptide starts from the N-terminal residue.

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
