In the boxes, draw the structures of $\text{M}$ and $\text{N}$.
Suggest suitable reagents and conditions for each stage of the synthesis. step $1$ step $2$ step $3$
Draw the structures of the two structural isomers with molecular formula $\text{C}_6\text{H}_{12}\text{N}_2\text{O}_5$ that may be present in the product mixture. The functional group formed in each one should be shown.
Predict how many different structural isomers with the molecular formula $\text{C}_9\text{H}_{19}\text{N}_3\text{O}_4$ may be present in the product mixture.
On the glutathione diagram, place an asterisk $(*)$ on each chiral centre.
Draw the structures of the three products formed by complete acid hydrolysis of glutathione. Assume the thiol group, $\text{-SH}$, does not react.
Glutathione dissolves in water. Using the structure of glutathione, explain why glutathione is soluble in water.
