Key to Xenobiotic Carotenoids [PDF]
A listing of carotenoids with heteroatoms (X = F, Cl, Br, I, Si, N, S, Se, Fe) directly attached to the carotenoid carbon skeleton has been compiled. The 178 listed carotenoids with C,H,X atoms demonstrate that the classical division of carotenoids into ...

This short review intends to present some key facts on carotenoids in a popular scientific language on the occasion of the International Year of Chemistry. Carotenoids have a characteristic C40H56 structure and represent a market value of several hundred million Euros. Their chemical synthesis is still a demanding challenge for chemists.

Aromatic carotenoids: Biological sources and geological implications
Aromatic carotenoids have been discovered in geological sections recording mass extinction events, oceanic anoxic events, and other geological abnormalities. Given their conventional biological source attribution to phototrophic sulfur bacteria, aromatic

Effect of Dietary Structure on Bioavailability and Antioxidant Activity of Citrus Carotenoids [PDF]
In order to explore the effect of different dietary structures (normal diet, high-protein diet, high-fat diet, high-sugar diet) on the bioavailability and antioxidant activity of citrus carotenoids, the changes in the carotenoid content, ferric reducing ...

Plasma concentrations of carotenoids and vitamin C are better correlated with dietary intake in normal weight than overweight and obese elderly subjects. [PDF]
Carotenoid and vitamin C intakes, assessed by FFQ, have been positively associated with plasma concentrations in different populations. However, the influence of BMI on these associations has not been explored in detail.

Fossil carotenoids and paleolimnology of meromictic Mahoney Lake, British Columbia, Canada [PDF]
Vertical distribution of fossil carotenoids in a sediment core from meromictic Mahoney Lake was studied. Besides okenone and demethylated okenone, lutein and zeaxanthin and-carotene isomers were identified.

Ruthenium porphyrin-ß-cyclodextrin complexes as supramolecular enzyme models for regioselective cleavage of carotenoids [PDF]
All naturally occurring vitamin A derives from enzymatic oxidative cleavage of β,β-carotene or other carotenoids with pro-vitamin A activity. Two metabolic pathways of β,β-carotene to retinal (vitamin A aldehyde) have been proposed: the central cleavage ...

Structures and functions of carotenoids bound to reaction centers from purple photosynthetic bacteria [PDF]
The photoprotective function of 15,15'-cis-carotenoids bound to the photosynthetic reaction centers (RCs) of purple bacteria has been studied using carotenoids reconstituted into carotenoidless RCs from Rhodobacter sphaeroides strain R26.1.
