Are the following molecules α-amino acids? Why?

i. The molecule is an α-amino acid because it has an amino group connected to the α-position relative to the carbonyl carbon.

ii. The molecule is not an α-amino acid because it does not have an amino group connected to the α-position relative to the carbonyl carbon.

iii. The molecule is not an α-amino acid because it does not have a carboxylic group.

i. The molecule is not an α-amino acid because it does not have a hydroxyl group connected to the α-position relative to the carbonyl carbon.
