What is the Origin of One-Carbon Metabolism?

The term accurately describes the core function of transferring one-carbon groups, a process that is integral to intermediary metabolism. The pathway's clinical significance gained prominence with the discovery of its role in folate deficiency and the link between impaired methylation and elevated homocysteine levels, a risk factor for cardiovascular disease, in the latter half of the 20th century. Research in nutritional biochemistry provided the key enzymatic details of the cycles.

What is the Mechanism of One-Carbon Metabolism?

The pathway is driven by a series of interconnected cycles, most prominently the folate cycle and the methionine cycle, which recycle the single-carbon units. Key enzymes, such as Methylenetetrahydrofolate Reductase (MTHFR), govern the flow of these units, converting them into the universal methyl donor, SAMe. SAMe then provides the methyl groups for countless reactions, including the methylation of DNA, histones, and numerous hormones and neurotransmitters, effectively linking nutrient status to gene expression and endocrine signaling efficiency.

One-Carbon Metabolism

Meaning

One-Carbon Metabolism is a crucial, interconnected network of biochemical reactions involving the transfer of single-carbon units, primarily derived from folate and choline, to various acceptor molecules within the cell. This metabolic pathway is essential for fundamental cellular processes, including the synthesis of nucleotides for DNA and RNA, the production of S-adenosylmethionine (SAMe) for widespread methylation reactions, and the detoxification of the amino acid homocysteine. Optimal one-carbon metabolism is vital for genomic stability, epigenetic regulation, and neurotransmitter synthesis, directly impacting hormonal health and longevity.
