ALSUntangled # 69: astaxanthin

Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration, 2023
ALSUntangled reviews alternative and off-label treatments for people living with amyotrophic lateral sclerosis (PALS). Here we review astaxanthin which has plausible mechanisms for slowing ALS progression including antioxidant, anti-inflammatory, and anti-apoptotic effects.

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 ...

Astaxanthin

2023
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 ...

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 ...

Hydrophilic Astaxanthin: PEGylated Astaxanthin Fights Diabetes by Enhancing the Solubility and Oral Absorbability

Journal of Agricultural and Food Chemistry, 2020
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 in the Cedar Waxwing

Science, 1963
The 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 Production from Microalgae

2020
Astaxanthin is commercially sold as a pigment for animal feed and as an antioxidant for the nutraceutical sector. Astaxanthin is predominantly manufactured synthetically from petrochemicals but is also obtained from the chlorophyte Haematococcus pluvialis (Haematococcus lacustris). The petrochemical-derived synthetic alternative has conventionally been

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-
