The carotenoids as anti-oxidants--a review.
Carotenoids are abundant in many fruits and vegetables and they play diverse roles in photobiology, photochemistry and medicine. This review concerns the reactivity of carotenoids with singlet oxygenExpand

Carotenoid radical chemistry and antioxidant/pro-oxidant properties.
The purpose of this review is to summarise the current state of knowledge of (i) the kinetics and mechanisms of radical reactions with carotenoids, (ii) the properties of carotenoid radicals, andExpand

Blue light-induced singlet oxygen generation by retinal lipofuscin in non-polar media.
Accumulation of lipofuscin (LF) is a prominent feature of aging in the human retinal pigment epithelium (RPE) cells. This age pigment exhibits substantial photoreactivity, which may increase the riskExpand

Singlet oxygen quenching by dietary carotenoids in a model membrane environment.
The ability of several dietary carotenoids to quench singlet oxygen in a model membrane system (unilamellar DPPC liposomes) has been investigated. Singlet oxygen was generated in both the aqueous andExpand

Singlet oxygen quenching and the redox properties of hydroxycinnamic acids.
The singlet oxygen quenching rate constants (kq) for a range of hydroxycinnamic acids in acetonitrile and D2O solutions were measured using time resolved near infrared phosphorescence in order toExpand

Energy transfer between the carotenoid and the bacteriochlorophyll within the B-800-850 light-harvesting pigment-protein complex of Rhodopseudomonas sphaeroides.
Energy transfer between carotenoid and bacteriochlorophyll has been studied in isolated B-800-850 antenna pigment-protein complexes from different strains of Rhodopseudomonas sphaeroides whichExpand

A pulse radiolysis investigation of the oxidation of the melanin precursors 3,4-dihydroxyphenylalanine (dopa) and the cysteinyldopas.
The unstable quinones of 3,4-dihydroxyphenylalanine (dopa) and the most abundant cysteinyldopa isomers (2S-, 5S- and 2,5S,S'-) have been generated rapidly via disproportionation of their respectiveExpand

The singlet oxygen and carotenoid interaction.
Second-order rate constants kQ for the quenching of O2(1 delta g) by carotenoids were determined at room temperature in benzene and toluene using the technique of time-resolved luminescence. Of theExpand
