Why is the dehydration synthesis also called a condensation reaction?

    Doesn't condensation imply a change from a gas to a liquid?

    Were the nucleotides gases when the phosphodiester bond formed?
    Were the amino acids gases when the peptide bond formed?

    It is just the same name used for two different processes. In latin condensatio means to thicken, it happens that it fits both cases.

    The formation of the peptide bond is called a condensation reaction since one H2O is produced when two amino acids bond.
    The NH3 amine group donates one H and the COOH acid group donates an
    OH . The peptide bond then is between N-C
