Remethylation of homocysteine (HCYS) to methionine (L-Met) can also proceed by using betaine (BET) as a methyl donor, which is oxidised to dimethylglycine (DMGLY). This reaction is also part of choline catabolism, thereby providing a link to folate-dependent, one-carbon metabolism (Li et al. 2008).
