Carotenoid β-Ring Hydroxylase and Ketolase from Marine Bacteria—Promiscuous Enzymes for Synthesizing Functional Xanthophylls [PDF]
Marine Drugs, 2011 Marine bacteria belonging to genera Paracoccus and Brevundimonas of the α-Proteobacteria class can produce C40-type dicyclic carotenoids containing two β-end groups (β rings) that are modified with keto and hydroxyl groups.

Antioxidant activities of carotenes and xanthophylls [PDF]
FEBS Letters, 1996 The purpose of this study was to assess the relative antioxidant activities of a range of carotenes and xanthophylls through the extent of their abilities to scavenge the ABTS·+ radical cation. The results show that the relative abilities of the carotenoids to scavenge the ABTS·+ radical cation are influenced by the presence of functional groups with ...

The impact of selected xanthophylls on oil hydrolysis by pancreatic lipase: in silico and in vitro studies [PDF]
Scientific ReportsLipase inhibition is one of the directions to control obesity. In vitro assays have confirmed the inhibitory effect of selected xanthophylls, including astaxanthin, fucoxanthinol, fucoxanthin, and neoxanthin.

How do xanthophylls protect lipid membranes from oxidative damage? [PDF]
, 2023 Here, we address the problem of the antioxidant activity of carotenoids in biomembranes. The activity of lutein and zeaxanthin in the quenching of singlet oxygen generated by photosensitization was monitored in lipid vesicles using a singlet oxygen ...

Yolks color definition by supplementing yellow and red xanthophylls to hen's diets [PDF]
, 2014 Egg yolk color may be controlled both by the concentration and the type of xanthophylls added to diets, with the aim of meeting consumers demand. The objectives of this work were to study how yellow and red xanthophylls present in laying hens` diets ...

Use of natural pigments obtained from cyanobacteria and algae
Acta et Commentationes: Ştiinţe Exacte şi ale Naturii, 2022 The article reflects data on the use of cyanobacteria pigments in cosmetology. One of the sources of natural antioxidants are the pigments obtained from various algae and cyanobacteria. An essential source for extracting pigments and biologically active
