Photochemistry and Photobiology, 1996
Carotenoids are usually considered to perform two major functions in photosynthesis. They serve as accessory light harvesting pigments, extending the range of wavelengths over which light can drive photosynthesis, and they act to protect the chlorophyllous pigments from the harmful photodestructive reaction which occurs in the presence of oxygen ...

Nutrition Reviews, 2009
Interactions between carotenoids during absorption and during postabsorptive metabolism have been demonstrated or suggested in animal and human feeding or supplementation studies, as well as in in vitro studies of intestinal beta-carotene cleavage.

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.

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 ...

Photoprotection by carotenoids
Journal of Ethnopharmacology, 1988Carotenoid pigments have been found to have a protective function against photosensitization in green plants. This protective ability has been exploited in the administration of high doses of beta-carotene to patients with erythropoietic protoporphyria to ameliorate the photosensitivity associated with this disease.

Carotenoids and Photosynthesis
2016Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis.

Summary.After a brief discussion of the essential chemical properties of carotenoids, the identification, occurrence and distribution of the pigments in the gonads and related organs of plants and animals have been reviewed. The information available concerning the metabolism of carotenoids in reproductive tissues and their possible function in ...

Nutrition, 2001
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 ...
