Betaine is synthesized by a two-step oxidation of choline in which mitochondrial choline oxidase first catalyzes the production of betaine aldehyde, which is further oxidized by mitochondrial betaine aldehyde dehydrogenase to betaine (Dragolovich, 1994).
An important metabolic pathway for choline involves its conversion into glycine via betaine aldehyde, betaine, N,N-dimethylglycine (DMG) [6] and sarcosine (Fig.
