Dietary antioxidants such as carotenoids, tocopherols, vitamin C or flavonoids exhibit biological activities that are not directly related to their antioxidant properties. The parent compounds and/or their metabolites have impact on cellular signaling pathways, influence the expression of certain genes or ...
The antioxidant effects of β-carotene, oil-soluble (bixin) and water-soluble (norbixin) annatto preparations and mixtures of these carotenoids with virgin olive oil polar extract were assessed in bulk olive oil and oil-in-water emulsions stored at 60 °C. Norbixin was the only carotenoid that...
The antioxidant properties of carotenoids may support cardiovascular functions. The protection of the arterial walls and management of healthy blood cholesterol levels are the primary mechanisms for this benefit. Eye Health Support Carotenoid may help to maintain the macula in the eyes, which often dege...
These health benefits have originally been ascribed to their anti-inflammatory/antioxidant properties, as carotenoids can protect against lipid peroxidation and damage caused by reactive oxygen species (ROS) [5]. In the past decade, there has been a great interest to understand how carotenoids, or ...
Carotenoids and retinoids have several similar biological activities such as antioxidant properties, the inhibition of malignant tumour growth and the induction of apoptosis. Supplementation with carotenoids can affect cell growth and modulate gene expression and immune responses. Epidemiological studies have ...
CHAPTER 8:Carotenoids: Concept, Dietary Sources and Structure–Activity Relationships for Antioxidant and Health-related Properties with primary and secondary formed compounds are discussed, as well as some food dietary sources, intake of carotenes and xanthophylls and the structure鈥揳ctivity relationships...
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 ...
have engineered the tobacco carotenoid biosynthetic pathway to produce the marine compound astaxanthin, a red pigment of considerable economic and nutritional value because of its antioxidant properties. By introducing a β-carotene ketolase from the alga Haematococcus pluvialis into tobacco under the ...

5,5-Dimethyl-pyrroline- N-oxide (DMPO) and N-tert-butyl-α-phenylnitrone (PBN) were used as spin traps for the EPR studies. The results show that the scavenging ability of the carotenoids towards radical OOH correlates with their redox properties. 展开 关键词:...
