A. Draw the backbone of tripeptide that is in the beta sheet conformation. Your tripeptide should be three amino
acids long, and should show all backbone atoms (you can abbreviate the R group as "R"). Assume pH 7.4 and show + and - charges.
B. Next to the tripeptide you drew above, draw a second tripeptide, also in the beta sheet conformation, and interacting with the first tripeptide. Draw the second tripeptide so that the two chains interact in the anti-parallel orientation. circle any hydrogen bond that might be present
