Additional studies have continued to refine our understanding of this function. Because carotenoids are excellent scavengers of singlet oxygen and respectable scavengers for other reactive oxygen species, substantial work was done concerning their potential role as antioxidants. In an unexpected...
positively correlated with a reduced risk of exudativeage-related macular degeneration (AMD). The concentration of these carotenoids in the bloodserum is also positively correlated with macular pigment density. Taken together, theseÆndings suggest a protective function for the macular pigment against ...
Carotenoid Synthesis and Function in Plants: Insights from Mutant Studies in Arabidopsis thaliana Carotenoids are integral components of higher plant photosystems and their composition in photosynthetic plant tissues (lutein, 尾-carotene, violaxanthin a...

What is the main function of the carotenoids? The main function of carotenoids is to act as an antioxidant in destroying the free radicals that are harmful to the body. They have a pro-vitamin A function where beta-carotene and alpha-carotene contribute to the activity of retinol. Beta-carot...
(Sun et al.2020b). While the gain-of-function alleles ofORpromote chromoplast biogenesis, only one or two large chromoplasts are present in each affected cell (Li et al.2001; Chayut et al.2017). The natural variant of OR found in melon, ORHis, was discovered to specifically interact...
Carotenoids are provenimmune system boosters. In fact, higher carotenoid intake isassociatedwith improvements in several biomarkers of strong immune function. Carotenoids have anti-inflammatory, antitumor, chemoprotective properties that help us ward off common infections, illnesses and serious diseases like...
Ingestion of calorie-rich foods, sedentary life-style counpled with energy disparity is leading towards obesity and related complications in humans. Many preclinical and clinical studies confirm anti-obesity properties of functional foods lie carotenoids. This chapter highlights recent information on the ...
Other than the stunning visual colors of carotenoids, what is their natural role of these compounds in nature? Carotenoids avoid oxidative damage (antioxidant function) of cells and cellular organelles by quenching the scavenging singlet oxygen molecules, peroxy radicals, and other toxic oxygen species...
Gaps in our knowledge include elucidating causal relationships between carotenoids and the mechanisms discussed herein. They also include questions on the effects of apo-carotenoids on GM, the structure and potential function of bacterially-derived metabolites, and also to what extent carotenoids or apo...
Whatever the results of these trials, carotenoids clearly show biological actions in animals distinct from their function as precursors of vitamin A.doi:10.1096/fasebj.3.8.2656356Adrianne BendichClinical NutritionHoffmann‐LaRoche, Inc.NutleyNew Jersey07110USAJames Allen Olson...
