Although one methyl group is only attached to the thorium atom (Th–C distance 257.1 pm) and the other six connect the lithium and thorium atoms (Th–C distances 265.5–276.5 pm) they behave equivalently in solution.
As a result of the transfer of the methyl group, S-adenosyl-homocysteine is obtained.
And in the case of DNA, by adding this methyl group or this tag, however you want to think about it, you’re actually turning genes on or off.
For example, three isomers exist for cresol because the methyl group and the hydroxyl group can be placed next to each other (ortho), one position removed from each other (meta), or two positions removed from each other (para).
Seventy percent of the DNA in any human genome is methylated, meaning it contains methyl group modifications within a CpG dinucleotide context.
Free radical reactions When placed in benzylic or allylic positions, the strength of the C-H bond is decreased, and the reactivity of the methyl group increases.
