Faba bean (Vicia faba L.) has been identified as a rich source of l-DOPA, which is used in treating Parkinson's disease. Biosynthesis and accumulation of active substances such as l-DOPA in plant tissues may interact with growing conditions and ...

L-Dopa and Schizophrenia [PDF]
Previous reports have emphasized the deterioration of schizophrenic patients when given L-Dopa. The authors described a patient with long-standing catatonic schizophrenia who was not helped by conventional therapies but initially responded dramatically to L-Dopa.

Inactivation of Tyrosinase by Dopa
Tyrosinase in a melanosome is known to be inactivated during melanin formation in vivo, and a similar inactivation was observed in vitro when melanosomes isolated from Harding Passey mouse melanoma were incubated with dopa. Tyrosinase, whether particle bound or in soluble form, was inactivated during the dopa-tyrosinase reaction and the reduction rate ...

L-Dopa and the albino riddle: content of L-Dopa in the developing retina of pigmented and albino mice. [PDF]
The absence or deficiency of melanin as in albinos, has detrimental effects on retinal development that include aberrant axonal projections from eye to brain and impaired vision. In pigmented retinal pigment epithelium (RPE), dihydroxyphenalanine (L-Dopa)

Catecholamine Derivatives as Novel Crosslinkers for the Synthesis of Versatile Biopolymers
Catecholamine metabolites are not only involved in primary metabolism, but also in secondary metabolism, serving a diverse array of physiologically and biochemically important functions. Melanin, which originates from dopa and dopamine, found in the hair,

A promising material for bone repair: PMMA bone cement modified by dopamine-coated strontium-doped calcium polyphosphate particles [PDF]
Polymethyl methacrylate (PMMA) bone cement has been widely used in clinics as bone repair materials for its excellent mechanical properties and good injection properties. However, it also has defects such as poor biological performance, high temperature,

Reactions of DOPA (3,4-dihydroxyphenylalanine) decarboxylase with DOPA [PDF]
The study of DOPA (3,4-dihydroxyphenylalanine) decarboxylase by steady-state methods is difficult because multiple reactions occur. The reaction with DOPA was studied at enzyme concentrations between 20 and 50 micrometer by direct observation of the bound coenzyme by using stopped-flow and conventional spectrophotometry. Four processes were observed on

L-DOPA functions as a plant pheromone for belowground anti-herbivory communication [PDF]
While mechanisms of plant–plant communication for alerting neighbouring plants of an imminent insect herbivore attack have been described aboveground via the production of volatile organic compounds (VOCs), we are yet to decipher the specific components ...

Pyrylium based derivatization imaging mass spectrometer revealed the localization of L-DOPA.
Simultaneous imaging of l-dihydroxyphenylalanine (l-DOPA), dopamine (DA) and norepinephrine (NE) in the catecholamine metabolic pathway is particularly useful because l-DOPA is a neurophysiologically important metabolic intermediate.
