It can be converted into two important active coenzymes, namely adenosyl cobalamin (AdoCbl) and methyl cobalamin (MeCbl), which play crucial roles in mitochondria and cytoplasm, respectively.
S-adenosylmethionine is synthesized from methionine, which is then catalyzed by adenosyl triphosphate cyclase, allowing methyl group donation to various substrates, including nucleic acids, proteins, phospholipids, and biogenic amines.
Ethanol inhibits methionine adenosyl transferase, which converts methionine into SAMe, as well as enzymes that help regenerate methionine (i.e., betaine homocysteine methyltransferase and methionine synthase) (Seitz and Sticke 2007).
Met is converted into AdoMet by catalytic actions of two isoenzymes, MATI and MATIII, of methionine adenosyl transferase [2, 3].
Amdl (Adenosyl methionine decarboxylase) is required for the synthesis of the polyamines spermine and spermidine.

Transfer of an adenosyl group to [Cbl.sup.I] via the action of adenosyl-transferase produces adenosyl cobalamin.
It is an intermediate in the synthesis of methionine, and methyl group donor, S adenosyl methionine.
Yasko provides detailed charts helping consumers and their doctors navigate the decision tree of whether to use adenosyl B12, hydroxy B12 or methyl B12, as well as combinations of these different forms.
Hepatocytes were isolated and cultured, and carbon monoxide (CO) and nitric oxide (NO) release, as well as adenosyl triphosphate (ATP), cyclic guanosyl monophosphate (cGMP), phosphatidylcholine (PC) and lipid peroxide (LPO) content of cells were evaluated.
