摘要: Contrary to previous reports, 5-methyltetrahydrofolic acid does not mediate the methylation of dopamine epinine. Instead, this methyl donor is degraded enzymatically formaldehyde, which condenses with form a tetahydoisoquinoline derivative. The latter has chromotographic characteristics very similar those epinine, likely accounts for original misidentification product.
