- In immunology, a conjugate vaccine
- In metabolism, conjugation is a biochemical process to bind a substance to an acid and thereby deactivating its biological activity, making it water-soluble, and facilitating its excretion.

- a conjugate acid-base pair is one base and one acid which differ from each other by one proton (H+), as defined by the Brønsted-Lowry acid-base theory
- In organic chemistry, a conjugated system is a system of atoms covalently bonded with alternating single and multiple bonds.
- In biochemistry: (see metabolism above)
