| There is also a reduction in the level of dopa metabolites when levodopa is combined with benserazide. |
| Studies have shown that peripheral dopa decarboxylase is saturated by carbidopa at doses between 70 to 150 mg per day. |
| They have measured the second-order electron transfer rate constants for reactions of dopa and c-dopa melanins with various radicals. |
| Betacynin biosynthesis starts by the oxidation of tyrosine to dopa by a tyrosine hydroxylase. |
| He was able to reverse this effect by giving the animals dopa, the amino acid precursor for dopamine. |
| Many autistic children have high levels of homocysteine, and methylating dopa increases homocysteine. |
