repulsion within the protein 10. Which of the following amino acids do not contain a chiral carbon? a. Proline b. Alanine c. Glycine d. Phenylalanine e. Tyrosine 11. You want to determine an amino acid sequence for a particular polypeptide. So you degrade the peptid and get the following fragments. Determine the peptide sequence.

On your internship, you visit the Mass Spectrometry Lab. Mass spectrometry can identify short peptide fragments based on their molecular weights. Your fellow intern Jerry has neglected to label his tubes of amyloid beta peptide 42 after digesting them with some proteases that we learned about in Module 6: pepsin, trypsin, and chymotrypsin. Help him figure out what protease is in each tube. Jerry’s supervisor has the fragments listed in the same order as the original peptide primary sequence, which...
