Methylated B12 and folate are crucial components in nutritional science for optimum health. The interactions between them emphasise their significance in energy metabolism, mental well-being and DNA production as they operate together mostly in the methylation cycle. Whether from well-balanced diets or ...

Because the conversion into active folate is not required for reduced and methylated folates like Quatrefolic®, it is a more effective form to take folate than folic acid, which requires conversion. It is also very beneficial for people with MTHFR polymorphism, since they have a lower ability...

Cobalamin, in the form of methylcobalamin, functions as a cofactor and 5-MTHF acts as a co-substrate for the enzyme methionine synthase (MS; EC 2.1.1,13) where homocysteine is methylated to methionine and 5-MTHF is converted to THF (Figure 4). This reaction is a critical step for the ...
6 Hcy is remethylated to regenerate methionine by the ubiquitous folate-dependent enzyme methionine synthase (MTR), using 5-methyltetrahydrofolate as the methyl donor. However, in liver and kidney, Hcy can also be remethylated through a folate-independent reaction catalyzed by betaine-Hcy ...
34 Within this pathway, homocysteine is remethylated to form methionine using the methyl from folate with vitamin B12 serving as a coenzyme.20 Insufficient folate and vitamin B12 can lead to increased homocysteine levels,21 which is harmful to the cardiovascular system.35 Thus, homocystei...

hMLH1 methylated tumours comprised the majority (81%) of cases with microsatellite instability, were frequently observed in older female patients, were often poorly differentiated or CIMP+, and contained wild-type K-ras (p<0.05 for each). Females who were heterozygous or homozygous for the C677...
1 Folate from diet or folic acid (FA) from supplements can donate a carbon group to homocysteine (Hcy), which can be either methylated into methionine or degraded into cysteine, with vitamins B6 and B12 serving as essential coenzymes.2 Emerging evidence suggests that low status of these B ...
