Astaroth (アスタロス, Asutarosu) is a fictional character in the Soul series of video games. Created by Namco's Project Soul division, he first appeared in the original Soulcalibur and its subsequent sequels, later appearing in various merchandise related to the series. He is voiced in Japanese by Banjō Ginga for Soulcalibur and Ryūzaburō Ōtomo in later titles; in all English-language versions of Soulcalibur II, Astaroth was voiced by Jay S.

Astaroth (アスタロス, Asutarosu) is a fictional character in the Soul series of video games. Created by Namco's Project Soul division, he first appeared in the original Soulcalibur and its subsequent sequels, later appearing in various merchandise related to the series. He is voiced in Japanese by Banjō Ginga for Soulcalibur and Ryūzaburō Ōtomo in later titles; in all English-language versions of Soulcalibur II, Astaroth was voiced by Jay S. Gilbert.Introduced in Soulcalibur, Astaroth is a golem created by a cult worshiping the Greek god of war Ares to locate a cursed sword named "Soul Edge". Though Astaroth has consistently pursued the sword, his character has changed as the series progresses, eventually transforming into a power hungering creature desiring to consume the sword. Regarded as an iconic character of the series, Astaroth has been noted as fitting a large character stereotype seen in fighting games, featuring strong attacks but slow speed. Astaroth has been described as having easy-to-master gameplay and being popular with fans of strong, hard-hitting characters in fighting games.

Astaxanthin is a keto-carotenoid. It belongs to a larger class of chemical compounds known as terpenes (in Asthaxanthin's case, a tetraterpenoid); terpenes are built from five carbon precursors; isopentenyl diphosphate (or IPP) and dimethylallyl diphosphate (or DMAPP).

Astaxanthin is a keto-carotenoid. It belongs to a larger class of chemical compounds known as terpenes (in Asthaxanthin's case, a tetraterpenoid); terpenes are built from five carbon precursors; isopentenyl diphosphate (or IPP) and dimethylallyl diphosphate (or DMAPP). Astaxanthin is classified as a xanthophyll (originally derived from a word meaning "yellow leaves" since yellow plant leaf pigments were the first recognized of the xanthophyll family of carotenoids), but currently employed to describe carotenoid compounds that have oxygen-containing moities, hydroxyl (-OH) or ketone (C=O), such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin and/or canthaxanthin, containing both hydroxyl and ketone functional groups.Like many carotenoids, astaxanthin is a colorful, lipid-soluble pigment. This colour is due to the extended chain of conjugated (alternating double and single) double bonds at the centre of the compound. This chain of conjugated double bonds is also responsible for the antioxidant function of astaxanthin (as well as other carotenoids) as it results in a region of decentralized electrons that can be donated to reduce a reactive oxidizing molecule.Astaxanthin is found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. It provides the red color of salmon meat and the red color of cooked shellfish. Professor Basil Weedon's group was the first to prove the structure of astaxanthin by synthesis, in 1975.Astaxanthin, unlike several carotenes and one other known carotenoid, is not converted to vitamin A (retinol) in the human body. Like other carotenoids, astaxanthin has self-limited absorption orally and such low toxicity by mouth that no toxic syndrome is known. It is an antioxidant with a slightly lower antioxidant activity in some model systems than other carotenoids. However, in living organisms the free-radical terminating effectiveness of each carotenoid is heavily modified by its lipid solubility, and thus varies with the type of system being protected.While astaxanthin is a natural dietary component, it can also be used as a food supplement. The supplement is intended for human, animal, and aquaculture consumption. The industrial production of astaxanthin comes from both natural and synthetic sources.The U.S. Food and Drug Administration (FDA) has approved astaxanthin as a food coloring (or color additive) for specific uses in animal and fish foods. The European Commission considers it food dye and it is given the E number E161j. Natural astaxanthin is generally recognized as safe (GRAS) by the FDA, meaning it can be sold as a dietary supplement, but as a food coloring in the United States it is restricted to use in animal food.
