The word ‘homocysteine’ has entered the lexicon of familiar words over the past decade, at least for health practitioners, as has the term methylation, and the two are intimately connected.

What is Methylation?

Methylation denotes 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, rather than a larger carbon chain, replacing a hydrogen atom. Methylation is catalysed by enzymes.
