S-Adenosylmethionine (SAM) is the universal methyl donor with an essential role in the survival of all organisms. SAM is at the heart of ancient pathways with two other key components, sulfur and iron atoms, that go back to the days of a world without atmospheric oxygen.

Why is S adenosyl methionine important?
S-Adenosylmethionine (SAM) is the universal methyl donor with an essential role in the survival of all organisms. SAM is at the heart of ancient pathways with two other key components, sulfur and iron atoms, that go back to the days of a world without atmospheric oxygen.
Where is S adenosyl methionine found?
the liver
S-Adenosyl methionine (SAM) is a common cosubstrate involved in methyl group transfers, transsulfuration, and aminopropylation. Although these anabolic reactions occur throughout the body, most SAM is produced and consumed in the liver.
Is S adenosyl methionine a protein?
Definition. Protein which binds at least one S-adenosyl-L-methionine (SAM), or protein whose function is SAM-dependent. S-adenosyl-L-methionine, a conjugate of the nucleotide adenosine and the amino acid methionine, is a substrate/cofactor in numerous enzyme-catalyzed reactions.
Is S adenosyl methionine an amino acid?
SAMe was discovered in the early 1950s. It’s made in the body from methionine, an amino acid found in foods. It has been found to regulate key functions in living cells. Abnormal levels of SAMe in the body have been reported in liver diseases and depression.
What is SAMe used for?
People most commonly take SAMe for depression and osteoarthritis. It is also used for anxiety, liver disease, fibromyalgia, schizophrenia, and many other conditions, but there is no good scientific evidence to support these uses.
Is SAMe safe to take?
More like a vitamin than a drug, SAM-e is a natural metabolite that the body needs more of as we age or if we become ill. SAM-e is generally safe and evidence-based for the treatment of depression. It is also a promising neuroprotectant and may be helpful in treating ADHD.
What is the role of AdoMet?
AdoMet is best known as the principal biological methyl donor. However, in addition to this well-recognized function, AdoMet is critically involved in the synthesis of polyamines. Polyamines are low-molecular-weight, positively charged molecules that are ubiquitous in all living cells (201).
