What is the definition and purpose of conjugate acids and bases?

Conjugate base- acid loses hydrogen, conjugate acid- base gains hydrogen

They are sort of opposites of each other.

Based on the Brønsted–Lowry acid–base theory, a conjugate acid is formed by a base receiving a proton. A conjugate base is the opposite - it is the base formed when the acid donates a proton.

So can a molecule become both a conjugate acid and base? If it gains a proton does that make it a conjugate acid, and if it loses a proton does that make it a conjugate base?

In a Conjugate Acid, the base gains hydrogens. and the Conjugated Base, the acid loses the hydrogen

Conjugate acid = A chemical compound formed by the reception of a proton by a base. It is a base with a hydrogen ion added to it.
Conjugate base = The species that is formed when an acid dissociates into its ions in water, it loses a hydrogen ion.

Conjugate bases are with respect to their original acids, and conjugate acids are with respect to their original bases. So conjugate acids/bases are that of another compound, they are always in relation. A conjugate acid would have to come from a base, while a conjugate base would have to come from an acid.
