Methylation - Wikipedia
Methylation, in the chemical sciences, is the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. Methylation is a form of alkylation, with a methyl group replacing a hydrogen atom. These terms are commonly used in chemistry, biochemistry, soil science, and biology.

Methylation | Biochemistry, Genetics & Epigenetics | Britannica
Methylation, the transfer of a methyl group (―CH3) to an organic compound. Methyl groups may be transferred through addition reactions or substitution reactions; in either case, the methyl group takes the place of a hydrogen atom on the compound. Methylation can …
Methylation: An Ineluctable Biochemical and Physiological …
Methylation is a universal biochemical process which covalently adds methyl groups to a variety of molecular targets. It plays a critical role in two major global regulatory mechanisms, epigenetic modifications and imprinting, via methyl tagging on histones and DNA.
Methylation - an overview | ScienceDirect Topics
Methylation involves transfer of a methyl group from S-adenosyl-l-methionine to lysine or arginine. Methylation/demethylation has been associated with a wide range of biological phenomena that include transcriptional regulation, heterochromatin formation, X-chromosome inactivation, as well as DNA methylation.
Methylation - an overview | ScienceDirect Topics
Methylation refers to the reversible process of adding methyl groups to DNA or RNA, which can impact gene expression and protein synthesis. In the context of neuroscience, methylation plays a crucial role in modulating gene-environment interactions and influencing various cellular processes related to RNA stability, transport, and translation.
Methylation: Definition and Examples - Chemistry Learner
Methylation is the process of adding a methyl group to a molecule. Methyl is either added to the substrate or replaced with another functional group. It can be considered a particular case of alkylation in which a methyl group is transferred.
