A common way of demethylation is the replacement of a methyl group by a hydrogen atom, resulting in a net loss of one carbon and two hydrogen atoms. The counterpart of demethylation is methylation. See more In biochemical systems, the process of demethylation is catalyzed by demethylases. These enzymes oxidize N-methyl groups, which occur in histones and some forms of DNA: R2N-CH3 + O → … See more Demethylation often refers to cleavage of ethers, especially aryl ethers, although there are some exceptions, such as N-demethylation of … See more • Methylation, the addition of a methyl group to a substrate See more coruche ribatejo
