It belongs to a larger class of chemical compounds known as terpenes in Asthaxanthins 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 CO, such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin andor 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 Weedons group was the first to prove the structure of astaxanthin by synthesis, in 1. 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 E1. Natural astaxanthin is generally recognized as safe GRAS by the FDA, meaning it can be sold as a dietary supplement,91. United States it is restricted to use in animal food. Natural sourcesedit. The shell and smaller parts of the bodily tissue of Pandalus borealis Arctic shrimp is colored red by astaxanthin, and is used and sold as a natural source of astaxanthin. Krill is also used as an astaxanthin source. Astaxanthin is present in most red coloured aquatic organisms. The content varies from species to species, but also from individual to individual as it is highly dependent on diet and living conditions. Astaxanthin, and other chemically related asta carotenoids, has also been found in a number of lichen species of the arctic zone. The primary natural sources for industrial production of astaxanthin comprise the following Astaxanthin concentrations in natural sources as found in nature are approximately Algae are the primary natural source of astaxanthin in the aquatic food chain. The microalgae Haematococcus pluvialis seems to accumulate the highest levels of astaxanthin in nature and is currently, the primary industrial source for natural astaxanthin production where more than 4. Haematococcus pluvialis has the productional advantage of the population doubling every week, which means scaling up is not an issue. However, it does require some expertise to grow the algae with a high astaxanthin content. Specifically, the microalgae are grown in two phases. First, in the green phase, the cells are given an abundance of nutrients to promote proliferation of the cells. In the subsequent red phase, the cells are deprived of nutrients and subjected to intense sunlight to induce encystment carotogenesis, during which the cells produce high levels of astaxanthin as a protective mechanism against the environmental stress. The cells, with their high concentrations of astaxanthin, are then harvested. Phaffia yeast Xanthophyllomyces dendrorhous exhibits 1. In contrast to synthetic and bacteria sources of astaxanthin, yeast sources of astaxanthin consist mainly of the 3. R, 3R form, an important astaxanthin source in nature. Finally, the geometrical isomer, all E, is higher in yeast sources of astaxanthin, as compared to synthetic sources. This contributes to greater efficacy because the all E trans isomer has greater bio availability than the cis isomer. In shellfish, astaxanthin is almost exclusively concentrated in the shells, with only low amounts in the flesh itself, and most of it only becomes visible during cooking, as the pigment separates from the denatured proteins that otherwise binds it. Astaxanthin is extracted from Euphausia superba Antarctic krill1. Synthetic sourceseditNearly all commercially available astaxanthin for aquaculture is produced synthetically, with an annual turnover of over 2. July 2. 01. 2. 1. The market grew to over 5. However, synthetic production of astaxanthin is not preferred in some cases because synthetic astaxanthin contains a mixture of stereoisomers. Astaxanthin is fairly abundant and easily obtainable from natural sources, and some consumers prefer natural astaxanthin, and natural products in general, over synthetic ones.
