al·kyl·a·tion

(al'ki-lā'shŭn),
Substitution of an alkyl radical for a hydrogen atom; for example, introduction of a side chain into an aromatic compound.

alkylation

/al·kyl·a·tion/ (al″kĭ-la´shun) the substitution of an alkyl group for an active hydrogen atom in an organic compound.

alkylation

a chemical reaction in which an alkyl group is transferred from an alkylating agent. When such organic reactions occur with a biologically significant cellular constituent such as deoxyribonucleic acid, they result in interference with mitosis and cell division.
