Carotenoids and their isomers: color pigments in fruits and vegetables.
Fruits and vegetables are colorful pigment-containing food sources. Owing to their nutritional benefits and phytochemicals, they are considered as 'functional food ingredients'. Carotenoids are some of the most vital colored phytochemicals, occurring as all-trans and cis-isomers, and accounting for the brilliant colors of a variety of fruits and vegetables. Carotenoids extensively studied in th...
متن کاملCarotenoids in ornamental fish farming
The aquaculture industry has grown dramatically in recent years, with a multimillion-dollar market. There are a variety of freshwater fish, marine fish, mollusks, and ornamental fish cultivated in this industry. The pigment and coloring of ornamental fish are important characteristics for marketing. In edible fish, carotenoids are responsible for the pigmentation of body tissue, while in ...
متن کاملA highly selective biosynthetic pathway to non-natural C50 carotenoids assembled from moderately selective enzymes
Synthetic biology aspires to construct natural and non-natural pathways to useful compounds. However, pathways that rely on multiple promiscuous enzymes may branch, which might preclude selective production of the target compound. Here, we describe the assembly of a six-enzyme pathway in Escherichia coli for the synthesis of C50-astaxanthin, a non-natural purple carotenoid. We show that by judi...
متن کاملSuperlative carotenoids.
A selection of carotenoids beyond normal appearance or properties has been presented at the 16(th) International Symposium on Carotenoids. Some of the exceptional compounds shown at the conference cannot be reproduced in this proceeding since they have not yet been published. In addition, editorial space limitation does not allow illustrating all of the previously mentioned carotenoids.
متن کاملAntioxidant activity of carotenoids.
Carotenoids are pigments which play a major role in the protection of plants against photooxidative processes. They are efficient antioxidants scavenging singlet molecular oxygen and peroxyl radicals. In the human organism, carotenoids are part of the antioxidant defense system. They interact synergistically with other antioxidants; mixtures of carotenoids are more effective than single compoun...
