[7] [24] This is one of several examples of the reciprocal regulation of PEMT and CT in the PEMT and CDP-choline pathways. Estrogen has also been shown to be a positive regulator of hepatocyte PEMT transcription. Ablation of the estrogen binding site in the PEMT promoter region may increase risk of hepatic steatosis from choline deficiency. [25]
The Methionine Synthase Reductase (MTRR) gene primarily acts in the reductive regeneration of cob(I)alamin (vitamin B12). [10] Cob(I)alamin is a cofactor that maintains activation of the methionine synthase enzyme (MTR) Methionine synthase, linking folate and methionine metabolism. Donation of methyl groups from folate are utilized for cellular ...
[1] [full citation needed] Choline is essential for fat metabolism. Choline functions as a methyl donor and it is required for proper liver function. Though choline can be synthesized from methionine or serine, mammals don't produce a sufficient amount on their own. Liver, eggs, wheat bran, meat, and broccoli are dietary sources of choline.
Methionine ball and stick model spinning. Methionine (symbol Met or M) [3] (/ m ɪ ˈ θ aɪ ə n iː n /) [4] is an essential amino acid in humans.. As the precursor of other non-essential amino acids such as cysteine and taurine, versatile compounds such as SAM-e, and the important antioxidant glutathione, methionine plays a critical role in the metabolism and health of many species ...

Methionine, an essential sulfur containing amino acid. The recommended daily allowance (RDA) of methionine (combined with cysteine) for adults is set at 13–14 mg kg-1 day-1 (13–14 mg per kg of body weight per day), but some researchers have argued that this figure is too low, and should more appropriately be 25 mg kg-1 day-1.

An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized from scratch by the organism fast enough to supply its demand, and must therefore come from the diet. Of the 21 amino acids common to all life forms, the eight amino acids humans cannot synthesize are valine , leucine , methionine , phenylalanine ...
