Interestingly, microbes can synthesize the active methylfolate form.[ref][ref][ref] Lets switch gears and look specifically at how your genetic variants are likely to interact with homocysteine levels
Role of Carnitine in the Oxidation of Fatty Acids L-carnitine is important in fatty acid metabolism in the brain, although fatty acid oxidation in nervous tissue is less important than glucose oxidation (in normal conditions, brain tissue does not use fatty acids as energy substrates because glucose is the basic brain fuel) [65]
6,7,8,9,10 NAD availability in the cytoplasm is a key determinant of the rate of NADH and pyruvate flux to mitochondria and, therefore, the rate of glycolysis
In particular, neurons of the gastrointestinal system are highly sensitive to oxidative stress (219, 225, 226), which is a general hallmark of TD (227)
