Carotenoids with two chromophores: carotenoid retinoates
Natural Product Research, 2011In this study, carotenoid retinoates are described for the first time. The preparation was achieved by the azolide method. Various sec carotenols reacted with N-retinoylimidazol in the presence of catalytic amounts of sodium hydride. Mono- and diretinoates of (3R,3'R)-zeaxanthin and its (3S,3'S)-enantiomer, (9Z,9'Z; 3R,3'R)-alloxanthin, (3R,3'R)-7,8,7',

C R C Critical Reviews in Food Science and Nutrition, 1987
In recent years, the results of research studies have suggested a positive beneficial relationship between a vegetarian-based diet and low incidence of diseases, including coronary heart disease, cancer, obesity, dental caries, and osteoporosis. beta-Carotene has specifically been suggested as a nutrient with antitumorigenic properties.

Archives of Biochemistry and Biophysics, 2004
The possible involvement of several transcription systems in the anticancer activity of carotenoids is the focus of this review. Carotenoids modulate the basic mechanisms of cell proliferation, growth factor signaling, gap junctional intercellular communication, and produce changes in the expression of many proteins participating in these processes ...

Carotenoids of the centrarchidae
Comparative Biochemistry and Physiology, 1970Abstract 1. 1. The carotenoid found in the skin and fins of eleven species of Centrarchids was identified as lutein, in the esterified form. 2. 2. Of the five genera, Lepomis generally has higher concentrations of pigment. 3. 3. Astaxanthin appears in the fins and skin of Lepomis megalotis during the breeding season.

SYNTHESIS OF CAROTENOID GLYCOSYLESTERS AND OTHER CAROTENOIDS
Pure and Applied Chemistry, 1979Abstract: The naturally occurring crocetin di(β-D-glucosyl)ester can be synthesised from crocetin diimidazolide or crocetin di-(1,2,4-triazolide) and β-D-glucose in pyridine in presence of a base. The application of this new method to other carboxylic acids (8′ -apo-β-carotene-8′-oic acid, vitamin A acid, benzoic acid and stearic acid) and ...

Larry Machlin had many and varied interests in nutrition in general and antioxidants in particular. Although he was interested primarily in vitamin E, he shared a curiosity about the actions of carotenoids that most nutritionists have. He served on the Organizing Committee of the 8th International Symposium on Carotenoids that was held in Boston in ...
