I think your main assumption is not true -- we do not really rest on weekends. I do not know many people who only rest on weekends. Usually this is the time for socializing, doing home-related work, physical activity (sports, hiking), spending time with your kids, all of which is often almost the op...

S-Adenosyl-L-homocysteine
{{DISPLAYTITLE:S-Adenosyl-L-homocysteine}}
S-Adenosyl-L-homocysteine (SAH) is the biosynthetic precursor to homocysteine. Adenosylhomocysteinase converts SAH into homocysteine and adenosine.
Biological role
DNA methyltransferases are inhibited by SAH.

Cysteine can be produced from methionine through a homocysteine intermediate, and defective genes for the enzymes involved can prevent proper cysteine production and cause a buildup of homocysteine.
