And that's precisely what our cells actually use this molecule for. This sand molecule is one of the more important donors of methyl groups inside our body. And whenever we want to methylate proteins, enzymes, neurotransmitter, hormones, and so forth, we can use this sam molecule. We can basically remove this methyl and attach it onto a target molecule. And that's exactly what happens in step two. So let's suppose we have some target molecule that we want to methylate and so we take the Sam.
