Free astaxanthin-rich diets enhanced astaxanthin accumulation in egg yolks compared to esterified astaxanthin-rich diets

Food Chemistry, 2023
As an oxycarotenoid with strong antioxidant properties, astaxanthin can considerably boost pigmentation and improve the nutritional value of eggs. The purpose of this study was to elucidate the comparative effects of different chemical structures of astaxanthin including free astaxanthin, monoester-enriched astaxanthin and diester-enriched astaxanthin ...

A Novel Radio-Tolerant Astaxanthin-Producing Bacterium Reveals a New Astaxanthin Derivative: Astaxanthin Dirhamnoside

2012
Astaxanthin is a red ketocarotenoid that exhibits extraordinary health-promoting activities such as antioxidant, anti-inflammatory, antitumor, and immune booster. The recent discovery of the beneficial roles of astaxanthin against many degenerative diseases such as cancers, heart diseases, and exercise-induced fatigue has raised its market demand as a ...

Astaxanthin in the American Flamingo

Nature, 1955
THE flamingo, Phoenicopterus ruber, derives from its dietary carotenoids the conspicuous rich pink to red colours of its feathers, tarsal and pedal skin and lower bill-mandible. Captive flamingos gradually lose their rich pigmentation unless appropriate dietary measures are taken. The presumptive role of crustacean carotenoids in supplying pigmentation

The biosynthesis of astaxanthin

International Journal of Biochemistry, 1970
Abstract A new keto carotenoid was isolated from goldfish ( Carssius auratus ) which was shown to be a 3-hydtoxy-3',4'-diketo-α-carotene. The name α-doradecin is proposed for the keto compound and doradexanthin for the esterified carotenoid, or mono keto compound. The carotenoids β-carotene, letein, α-doradecin, β-doradecin (3-hydroxy-3',4'-diketo-β-
