Answer:
1. D.
Condensation reaction always results in the formation of complex sugar (disaccharide or polysaccharide) and water.
2. B.
Classification. In addition to the amino and carboxyl groups, amino acids have a side chain or R group attached to the α-carbon. Each amino acid has unique characteristics arising from the size, shape, solubility, and ionization properties of its R group.
3. A.
Hydroxyl group is lost from its carboxyl group of one amino acid and a hydrogen atom is lost from its amino group of another amino acid.
Not that sure if this is correct
