Two -COOH compounds on opposite ends

[Renee Crippen 2I]

Is it possible to have compound with one -COOH group on each end of a linear compound?

If not, theoretically, would this remove the acidic properties of the compound?

Thanks,

I don't believe there is anything theoretically inhibiting the creation of such a molecule. Neither do I believe that such a molecule would inhibit the acidity present with just one COOH group, as its tendency towards acidity is due to the partial charges of the H and O of the OH group, which would not be affected by the presence of another COOH. If anything, would the existence of another source of H+ ion not make this hypothetical molecule more acidic?

There are many such molecules, they are suitably called the DIcarboxylic acids, and they are in fact, good organic acids that are diprotic (can donate two protons)
