Preliminary identification of the human macular pigment

Vision Research, 1985
The human macular pigment has been found to be composed to two chromatographically separable components, which are tentatively identified as lutein [(3R,3'R,6'R)-beta,epsilon-Carotene-3,3'-diol] and zeaxanthin [(3R,3'R)-beta,beta-Carotene-3,3'-diol]. Chromatograms of retinal extracts, obtained by HPLC on three different stationary phases, were found to

Identification of Yersinia pestis Pigment Receptor

2006
In the present work the PR of Y. pestis was identified as a complex of a 17 kDa protein associated with two oppositely charged low molecular weight components that cooperatively form a pigment binding domain of PR. The pigment binding activity of PR is dependent on an appropriate proportion of the low molecular weight components and on the absence of ...

Identification of Photoreceptor Pigments

2010
Rhodopsin, flavins, pterins and carotenoids are pigments that have been identified as participating in the photoreception and photomovement of eukaryotic algae [Lenci, 1975, 1995; Haupt and Hader, 1994; Kreimer, 1994; Lebert, 2001; Siebert, 2003]. Rhodopsin represents a protein (opsin), lipid and chromophore (retinal) complex.

Isolation and Identification of the Urinary Pigment Uroerythrin

European Journal of Biochemistry, 1975
The red pigment uroerythrin, a chromophore known to be adsorbed by the amorphous urate sediments (sedimentum lateritium), has been isolated from human urine and further purified as its trimethyl derivative.Urine was applied to a column of Amberlite XAD‐2 resin on which uroerythrin and other pigments were adsorbed. The pigments were eluted with methanol
