astaxanthin

Astaxanthin (trans-Astaxanthin) is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is present in most red-colored aquatic organisms. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive.

Astaxanthin monopalmitate (Astaxanthin palmitate) is an esterified form of astaxanthin, a type of carotenoid. Upon degradation, Astaxanthin monopalmitate yields a mixture of free and palmitate apo-astaxanthins. Carotenoids possess significant biological activity and may play roles in regulating cell differentiation, growth control, photoprotection, membrane stability, photosynthesis, vision, and nutrition.

Astaxanthin dipalmitate is a type of carotenoid. It can be used for coloring rainbow trout and sea trout. Carotenoids possess significant biological activities and may play roles in regulating cell differentiation, growth control, photoprotection, membrane stability, photosynthesis, visual processes, and nutrition.

Astaxanthin (Standard) is the standard substance of Astaxanthin, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Astaxanthin (trans-Astaxanthin) is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is present in most red-colored aquatic organisms. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive.

(rac./meso)-Astaxanthin (AstaREAL; AstaXin) is a carotenoid pigment primarily found in marine animals such as shrimp and salmon. It serves as an effective fat-soluble antioxidant.

7,8-Didehydroastaxanthin is the primary carotenoid found in the crown-of-thorns starfish. It is an oxidized metabolite of diatoxanthin. Carotenoids are crucial for biological activity and may play roles in regulating cell differentiation, growth control, photooxidative protection, membrane stability, photosynthesis, visual processes, and nutrition.

7,8,7’,8’-Tetradehydroastaxanthin is a glycopeptide that can be isolated from the carotenoid proteins of the red sea star (Asterias rubens).

Astacene is a key secondary carotenoid that can be extracted from the skin of goldfish and other species. It is an oxidation product of astaxanthin. Carotenoids possess significant biological activity and may play a role in cellular differentiation, growth regulation, photoprotection, membrane stability, photosynthesis, vision processes, and nutrition.

Idoxanthin is a metabolite of Astaxanthin. It plays a role in the carotenoid metabolism pathway, and its formation and accumulation indicate the metabolic capabilities and pathways in various fish species.

4-Hydroxyechinenone is a trace carotenoid found in crab shells. It is also an intermediate in the conversion of β-Carotene to Astaxanthin.
