Astaxanthin
Astaxanthin (pronounced as-tuh-zan-thin) is a carotenoid. It belongs to a larger class of phytochemicals known as terpenes. It is classified as a xanthophyll, which means "yellow leaves". Like many carotenoids, it is a colorful, lipid-soluble pigment. Astaxanthin is produced by microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. Professor Basil Weedon was the first to map the structure of astaxanthin.; Astaxanthin is the main carotenoid pigment found in aquatic animals. It is also found in some birds, such as flamingoes, quails, and other species. This carotenoid is included in many well-known seafoods such as salmon, trout, red seabream, shrimp, lobster, and fish eggs. Astaxanthin, similar to other carotenoids, cannot be synthesized by animals and must be provided in the diet. Mammals, including humans, lack the ability to synthesize astaxanthin or to convert dietary astaxanthin into vitamin A. Astaxanthin belongs to the xanthophyll class of carotenoids. It is closely related to beta-carotene, lutein, and zeaxanthin, sharing with them many of the general metabolic and physiological functions attributed to carotenoids. In addition, astaxanthin has unique chemical properties based on its molecular structure. The presence of the hydroxyl (OH) and keto (CdO) moieties on each ionone ring explains some of its unique features, namely, the ability to be esterified and a higher antioxidant activity and a more polar nature than other carotenoids. In its free form, astaxanthin is considerably unstable and particularly susceptible to oxidation. Hence it is found in nature either conjugated with proteins (e.g., salmon muscle or lobster exoskeleton) or esterified with one or two fatty acids (monoester and diester forms), which stabilize the molecule. Various astaxanthin isomers have been characterized on the basis of the configuration of the two hydroxyl groups on the molecule. the geometrical and optical isomers of astaxanthin are distributed selectively in different tissues and that levels of free astaxanthin in the liver are greater than the corresponding concentration in the plasma, suggesting concentrative uptake by the liver. Astaxanthin, similar to other carotenoids, is a very lipophilic compound and has a low oral bioavailability. This criterion has limited the ability to test this compound in well-defined rodent models of human disease. (PMID: 16562856); Astaxanthin is a carotenoid widely used in salmonid and crustacean aquaculture to provide the pink color characteristic of that species. This application has been well documented for over two decades and is currently the major market driver for the pigment. Additionally, astaxanthin also plays a key role as an intermediary in reproductive processes. Synthetic astaxanthin dominates the world market but recent interest in natural sources of the pigment has increased substantially. Common sources of natural astaxanthin are the green algae Haematococcus pluvialis, the red yeast, Phaffia rhodozyma, as well as crustacean byproducts. Astaxanthin possesses an unusual antioxidant activity which has caused a surge in the nutraceutical market for the encapsulated productand is) also, health benefits such as cardiovascular disease prevention, immune system boosting, bioactivity against Helycobacter pylori, and cataract prevention, have been associated with astaxanthin consumption. Research on the health benefits of astaxanthin is very recent and has mostly been performed in vitro or at the pre-clinical level with humans. (PMID: 16431409); Astaxanthin, unlike some carotenoids, does not convert to Vitamin A (retinol) in the human body. Too much Vitamin A is toxic for a human, but astaxanthin is not. However, it is a powerful antioxidant; it is claimed to be 10 times more capable than other carotenoids. However, other sources suggest astaxanthin has slightly lower antioxidant activity than other carotenoids.; While astaxanthin is a natural nutr...

Astaxanthin is used in fish farming to induce trout flesh colouring. Astaxanthin is a carotenone that consists of beta,beta-carotene-4,4-dione bearing two hydroxy substituents at positions 3 and 3 (the 3S,3S diastereomer). A carotenoid pigment found mainly in animals (crustaceans, echinoderms) but also occurring in plants. It can occur free (as a red pigment), as an ester, or as a blue, brown or green chromoprotein. It has a role as an anticoagulant, an antioxidant, a food colouring, a plant metabolite and an animal metabolite. It is a carotenone and a carotenol. It derives from a hydride of a beta-carotene. 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 found in the majority of aquatic organisms with red pigment. 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 is a natural product found in Ascidia zara, Linckia laevigata, and other organisms with data available. Astaxanthin is a natural and synthetic xanthophyll and nonprovitamin A carotenoid, with potential antioxidant, anti-inflammatory and antineoplastic activities. Upon administration, astaxanthin may act as an antioxidant and reduce oxidative stress, thereby preventing protein and lipid oxidation and DNA damage. By decreasing the production of reactive oxygen species (ROS) and free radicals, it may also prevent ROS-induced activation of nuclear factor-kappa B (NF-kB) transcription factor and the production of inflammatory cytokines such as interleukin-1beta (IL-1b), IL-6 and tumor necrosis factor-alpha (TNF-a). In addition, astaxanthin may inhibit cyclooxygenase-1 (COX-1) and nitric oxide (NO) activities, thereby reducing inflammation. Oxidative stress and inflammation play key roles in the pathogenesis of many diseases, including cardiovascular, neurological, autoimmune and neoplastic diseases.

Stercobilinogen
Stercobilinogen is a tetrapyrrole chemical compound that is the parent compound of stercobilin, the pigment that is responsible for the brown color of feces. Stercobilinogen is formed through the reduction of its parent compound uroblinogen. Urobilinogen is actually generated through the degradation of heme, the red pigment in haemoglobin and red blood cells (RBCs). RBCs have a life span of about 120 days. When the RBCs have reached the end of their useful lifespan, the cells are engulfed by macrophages and their constituents recycled or disposed of. Heme is broken down when the heme ring is opened by the enzyme known as heme oxygenase, which is found in the endoplasmic reticulum of the macrophages. The oxidation process produces the linear tetrapyrrole known as biliverdin along with ferric iron (Fe3+), and carbon monoxide (CO). In the next reaction, a second methylene group (located between rings III and IV of the porphyrin ring) is reduced by the enzyme known as biliverdin reductase, producing bilirubin. Bilirubin is significantly less extensively conjugated than biliverdin. This reduction causes a change in the color of the biliverdin molecule from blue-green (vert or verd for green) to yellow-red, which is the color of bilirubin (ruby or rubi for red). In plasma virtually all the bilirubin is tightly bound to plasma proteins, largely albumin, because it is only sparingly soluble in aqueous solutions at physiological pH. In the sinusoids unconjugated bilirubin dissociates from albumin, enters the liver cells across the cell membrane through non-ionic diffusion to the smooth endoplasmatic reticulum. In hepatocytes, bilirubin-UDP-glucuronyltransferase (bilirubin-UGT) adds 2 additional glucuronic acid molecules to bilirubin to produce the more water-soluble version of the molecule known as bilirubin diglucuronide. The bilirubin diglucuronide is transferred rapidly across the canalicular membrane into the bile canaliculi where it is then excreted as bile into the large intestine. The bilirubin is further degraded (reduced) by microbes present in the large intestine to form a colorless product known as urobilinogen. Urobilinogen that remains in the colon can either be reduced to stercobilinogen and finally oxidized to stercobilin, or it can be directly reduced to stercobilin. Stercobilinogen (aso known as L-urobilinogen) is closely related to two other compounds: mesobilirubinogen (also known as I-urobilinogen) and urobilinogen (also known as D-urobilinogen). Specifically, urobilinogen can be reduced to form mesobilirubinogen, and mesobilirubinogen can be further reduced to form stercobilinogen. Confusingly, however, all three of these compounds are frequently collectively referred to as "urobilinogens".
