acceptor

 [ak-sep´ter]
a substance that unites with another substance.
hydrogen acceptor the molecule accepting hydrogen in an oxidation-reduction reaction.

ac·cep·tor

(ak-sep'ter),
1. A compound that will take up a chemical group (for example, an amine, methyl, or carbamoyl group) from another compound (the donor); under the action of alanine transaminase, l-glutamate is an amine donor whereas pyruvate is an amine acceptor.
2. A receptor that binds a hormone.
3. A drug-binding receptor that has no identified endogenase ligand.
[L. ac-cipio, pp. -ceptus, to accept]

acceptor

/ac·cep·tor/ (ak-sep´ter) a substance which unites with another substance; specifically, one that unites with hydrogen or oxygen in an oxidoreduction reaction and so enables the reaction to proceed.
