A carotenoid-producing yeast strain, isolated from the sub-arctic, marine copepod Calanus finmarchicus, was identified as Rhodosporidium babjevae (Golubev) according to morphological and biochemical characteristics and phylogenetic inference from the

Monofluorinated polycyclic aromatic hydrocarbons (F-PAHs) have attracted much attention in analytical, environmental, toxicological and mechanistic studies because of their physico-chemical properties, which are closely similar to those of the parent

A series of charge-delocalized carotenoid mono- and dications have been prepared by treatment of selected carotenoids with Brønsted and Lewis acids. The detailed structures of the carbocations were established by NMR studies in the temperature range

It has been suggested that astaxanthin (3,3'-dihydroxy-beta,beta-carotene-4,4'-dione) in the carotenoprotein alpha-crustacyanin occurs in the diprotonated form. As a model system for protonated astaxanthin in [small alpha]-crustacyanin the reactions

The principal (96% of total) carotenoid in the novel, extremely halophilic eubacterium Salinibacter ruber, here called salinixanthin (1), has been assigned the structure (all-E,2'S)-2'-hydroxy-1'-[6-O-(13-methyltetradecanoyl)-beta-D-glycopyranosyloxy

Complete assignment of the 1 H and 13 C resonances of the methylchrysenes ( 1 - 6 ) were accomplished using 1D and 2D NMR techniques. Shift increments were calculated for the six mono -methyl isomers, showing the similarity of the positions 1 and 6,

The question raised in the title was answered. (3R, 3'S)-meso-Zeaxanthin was submitted to iodine catalyzed photochemical stereoisomerisation. The enantiomeric (9Z) and (9'Z) geometrical isomers were isolated by semipreparative HPLC and separated as d
