CAIE A-Level Chemistry A2 36.1.1 For an Organic Molecule Containing Several Questions question 1

[Maximum number: 2]

Asparagine and aspartic acid are two naturally occurring amino acids. Their structures and isoelectric points are shown in Table 8.1.

Table 8.1

Table 8.1

Asparagine and aspartic acid are treated separately with an excess of LiAlH4\mathrm{LiAlH}_{4}.

Draw the structures of the organic products of these reactions.
product of asparagine treated with an excess of LiAlH4\mathrm{LiAlH}_{4}
product of aspartic acid treated with an excess of LiAlH4\mathrm{LiAlH}_{4}
