Question

question 12 (1 point)
a(n)______ is a molecule that contains an amino group and a carboxyl group.
amide
nitrile
amine
amino acid
imine

Explanation:

An amino acid has the general formula \(R - CH(NH_2)-COOH\), which contains an amino group (\(-NH_2\)) and a carboxyl group (\(-COOH\)). An amide has the functional group \(-CONH_2\), a nitrile has \(-CN\), an amine has \(-NH_2\) but no carboxyl group, and an imine has \(C = N\) bond. So the molecule that contains both an amino group and a carboxyl group is an amino acid.

Answer:

amino acid
