What is the Origin of SAMe Cofactor?

The acronym SAMe stands for S-adenosylmethionine, highlighting its chemical structure. The term "cofactor" denotes its necessary role as a non-protein chemical compound that is bound to an enzyme and is required for catalysis. It is central to the one-carbon metabolism pathway.

What is the Mechanism of SAMe Cofactor?

SAMe facilitates the transfer of a methyl group to a substrate molecule, a process known as methylation. In the context of hormonal health, it is the required cofactor for Catechol-O-Methyltransferase (COMT), enabling the conversion of reactive catecholestrogens into their inactive methoxy-estrogen forms. Deficiencies in SAMe or its precursors can impair this detoxification, leading to an accumulation of potentially harmful estrogen intermediates.

SAMe Cofactor

Meaning

S-adenosylmethionine (SAMe) is a crucial, naturally occurring molecule that functions as the primary methyl-group donor in numerous biochemical reactions, including the critical methylation of estrogen metabolites. As a cofactor, SAMe is essential for the activity of methyltransferase enzymes. Its availability is directly linked to nutrient status and genetic factors, impacting detoxification and overall hormonal balance.
