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 ...

The biosynthesis of astaxanthin
International Journal of Biochemistry, 1970Abstract 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-

Astaxanthin is a lipid-soluble orange-red pigment in the family of the xanthophylls, which are the oxygenated derivatives of carotenoids, including β-cryptoxanthin, zeaxanthin, canthaxanthin, and lutein. Its molecular structure is similar to β-carotene and other carotenoids, but it does not have the biological activity of pro-vitamin A in the human ...

Astaxanthin in the Cedar Waxwing
Science, 1963The pigment on the secondary feathers of the cedar waxwing ( Bombycilla cedrorum ) is deposited as an amorphous layer upon a supporting medullary structure. The pigment was extracted with alkali and analyzed by chromatographic and spectrophotometric methods.

Astaxanthin in the American Flamingo [PDF]
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

To develop hydrophilic astaxanthin with significantly enhanced solubility and stability, astaxanthin polyethylene glycol succinate (APGS) was synthesized by esterification of an astaxanthin succinate diester with polyethylene glycol 1000. The chemical structure of the hydrophilic derivative was confirmed by 1H nuclear magnetic resonance and mass ...

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 ...

Journal of Agricultural and Food Chemistry, 1998
The reaction kinetics for the hydrolysis of astaxanthin esters and the degradation of astaxanthin during saponification of the pigment extract from the microalga Haematococcus pluvialis were investigated. Different concentrations of sodium hydroxide in methanol were used for the saponification under nitrogen in darkness at ambient temperature (22 ...
