Condensation reaction

A condensation reaction occurs as a result of two molecules bonding to each other, a smaller molecule is expelled.

When this smaller molecule is water ($\mathrm{H}_2\mathrm{O}$), a condensation reaction is known as dehydration; dehydration reactions are responsible for joining nucleotides into a strand} of nucleic acid as well as for linking amino acids into a polypeptide.
