Web25 Oct 2006 · Total serum homocysteine (tHcy) levels were significantly lower in controls than in both PD groups, giving rise to the overall difference observed (all genotypes included) ( P = 0.001; one-way ANOVA) ( Table 1 ). However, tHcy did not differ significantly between PD (− l -DOPA) and PD (+ l -DOPA) patients ( P > 0.05). WebMethylcobalamin, an activated form of vitamin B12, is a cofactor for methionine synthase which catalyzes the conversion of homocysteine to methionine and 5-methyltetrahydrofolate, a folate derivative, is a substrate. 15 Vitamin B12 or folate deficiencies may elevate circulating total homocysteine (tHcy) level which is a valuable …
