Mechanistic studies on tyrosinase-catalysed oxidative decarboxylation of 3,4-dihydroxymandelic acid.
Biochem. J. 281 ( Pt 2) , 353-7, (1992) Mushroom tyrosinase, which is known to convert a variety of o-diphenols into o-benzoquinones, has been shown to catalyse an unusual oxidative decarboxylation of 3,4-dihydroxymandelic acid to 3,4-dihydroxybenzaldehyde [Sugumaran (1986) Biochemistry 25, 4489-44... |

Oxidative decarboxylation of 3,4-dihydroxymandelic acid to 3,4-dihydroxybenzaldehyde: electrochemical and HPLC analysis of the reaction mechanism.
Biochim. Biophys. Acta 1077(3) , 400-6, (1991) Cyclic voltammetric and chronoamperometric data are consistent with a process in which 3,4-dihydroxymandelic acid (DOMA) is oxidized initially in a two-electron step to its corresponding o-benzoquinone. This species is unstable and undergoes the rate-determin... |

The influence of dietary restriction, germ-free status, and aging on adrenal catecholamines in Lobund-Wistar rats.
J. Gerontol. 46(4) , B135-41, (1991) Adrenal catecholamines (CA) were measured in 6-, 18-, and 30-mo Lobund-Wistar rats (LWR) maintained under germ-free or conventional conditions and fed either ad libitum or a restricted (70% of adult ad libitum) diet. Levels of dopamine (DA), norepinephrine (N... |
