catechol | 5 mM catechol results in a 5-8fold acceleration of the rate of oxidation of 2.5 mM L-Dopa | Bromus rubens | |
additional information | the presence of 5 mM of the following monophenolics has no effect on the rate of oxidation of 2.5 mM L-Dopa: 2-hydroxybenzoic acid (salicylic acid), 3-hydroxybenzoic acid, 4-hydroxybenzoic acid, (2-, 3-, or 4-)coumaric acids (2-, 3-, or 4-hydroxycinnamic acid). Additionally, neither 5 mM vanillin (4-hydroxy-3-methoxybenzaldehyde) nor pyrogallol (1,2,3-trihydroxybenzene) has any effect of the oxidation of 2.5 mM L-DOPA | Bromus inermis | |
