Compound P was discovered by a scientist. She discovered that P is a
tripeptide that is optically active and has the molecular formula C21H25N3O5.
As a part of the validation process, she tested compound P on different
scientific tests. When compound P is reacted with sodium hydroxide its
produced salt Q, C21H25N3NAO5 as a major product. Compound P also reacted
with sodium bicarbonate to produced salt R as a major product and two side
products. Both salts have a similar molecular formula. The reaction of
compound P with thionyl chloride produced compound S, C21H23Cl½N3O3.
Compound T is formed when compound P reacted with alcohol U, C4H100.
Identify the possible structural formulae for compounds P, Q, R, S, and T.
Label all peptide bonds for compound P.
Predict one (1) of the possible structural formulae of amino acid obtained
from compound P.
How would you distinguish between compound S and compound T?
