Modeling folate, one-carbon metabolism, and DNA methylation
29 Jul 2008
Abstract excerpt
The B-vitamin folate is essential for one-carbon transfer reactions. These include methylation reactions, such as the methylation of DNA or other substrates (by use of S-adenosylmethionine, SAM, which is concurrently converted to S-adenosylhomocysteine), and also the synthesis of thymidine and purines, which are needed for DNA synthesis and repair (see Figure 1).1 A protective role of folate early in...
