Carotenoids are among the most widely distributed pigments in nature, and they are exclusively synthesized by plants and microorganisms. These compounds may serve a protective role against many chronic diseases such as cancers, age-related macular degeneration, and cardiovascular diseases and also act as an excellent antioxidant system within cells ...

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 ...

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.

Biological Reviews, 1950
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 ...

Carotenoids occur universally in photosynthetic organisms but sporadically in nonphotosynthetic bacteria and eukaryotes. The primordial carotenogenic organisms were cyanobacteria and eubacteria that carried out anoxygenic photosynthesis. The phylogeny of carotenogenic organisms is evaluated to describe groups of organisms which could serve as sources ...

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.

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 ...

Carotenoids: Carotenoid and apocarotenoid analysis—Use of E. coli to produce carotenoid standards
2022Authentic samples of many carotenoids are commercially available, but are often too expensive and of insufficient purity. As an alternative, a wide range of carotenoids can be biosynthesized in recombinant Escherichia coli strains. E. coli cells naturally produce the carotenoid biosynthetic precursors and provide a blank slate for manufacturing ...

Carotenoids are a class of isoprenoids synthesized by all photosynthetic organisms as well as by some non-photosynthetic bacteria and fungi with broad applications in food, feed and cosmetics, and also in the nutraceutical and pharmaceutical industries.
