Paradol
Paradol is the active flavor constituent of the seeds of Guinea pepper ('' Aframomum melegueta'' or grains of paradise). It is also found in ginger. Paradol has been found to have antioxidant and antitumor promoting effects in a mouse model. It is used in flavors as an essential oil to give spiciness. See also * Gingerol * Shogaol Shogaols are pungent constituents of ginger similar in chemical structure to gingerol. The most common of the group is shogaol. Like zingerone, it is produced when ginger is dried or cooked. Moreover, shogaol (and gingerol) are converted to o ... References Phenol antioxidants Pungent flavors {{Aromatic-stub ...

Aframomum Melegueta
''Aframomum melegueta'' is a species in the ginger family, Zingiberaceae, and closely related to cardamom. Its seeds are used as a spice (ground or whole); it imparts a pungent, black-pepper-like flavor with hints of citrus. It is commonly known as grains of paradise, melegueta pepper, Guinea grains, ''ossame'', or ''fom wisa'', and is confused with alligator pepper. The term Guinea pepper has also been used, but is most often applied to ''Xylopia aethiopica'' (grains of Selim). It is native to West Africa, which is sometimes named the Pepper Coast (or Grain Coast) because of this commodity. It is also an important cash crop in the Basketo district of southern Ethiopia. Characteristics ''Aframomum melegueta'' is an herbaceous perennial plant native to swampy habitats along the West African coast. Its trumpet-shaped, purple flowers develop into pods long, containing numerous small, reddish-brown seeds. The pungent, peppery taste of the seeds is caused by aromatic keton ...

Ginger
Ginger (''Zingiber officinale'') is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice A spice is a seed, fruit, root, bark, or other plant substance primarily used for flavoring or coloring food. Spices are distinguished from herbs, which are the leaves, flowers, or stems of plants used for flavoring or as a garnish. Spice ... and a folk medicine. It is a herbaceous perennial plant, perennial which grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall bearing narrow leaf blades. The inflorescences bear flowers having pale yellow petals with purple edges, and arise directly from the rhizome on separate shoots. Ginger is in the family (taxonomy), family Zingiberaceae, which also includes turmeric (''Curcuma longa''), cardamom (''Elettaria cardamomum''), and galangal. Ginger originated in Maritime Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with ...

Antioxidant
Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals. This can lead to polymerization and other chain reactions. They are frequently added to industrial products, such as fuels and lubricants, to prevent oxidation, and to foods to prevent spoilage, in particular the rancidification of oils and fats. In cells, antioxidants such as glutathione, mycothiol or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress. The only dietary antioxidants are vitamins A, C, and E, but the term ''antioxidant'' has also been applied to numerous other dietary compounds that only have antioxidant properties in vitro, with little evidence for antioxidant properties in vivo. Dietary supplements marketed as antioxidants have not been shown to maintain health or prevent disease in humans. History As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouse Model
A model organism (often shortened to model) is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. Model organisms are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another. In researching human disease, model organisms allow for better understanding the disease process without the added risk of harming an actual human. The species chosen will usually meet a determined taxonomic equivalency to humans, so as to react to disease or its treatment in a way that resembles hu ...

Gingerol
Gingerol ( gingerol) is a phenolic phytochemical compound found in fresh ginger that activates spice receptors on the tongue. It is normally found as a pungent yellow oil in the ginger rhizome, but can also form a low-melting crystalline solid. This chemical compound is found in all members of the Zingiberaceae family and is high in concentrations in the grains of paradise as well as an African Ginger species. Cooking ginger transforms gingerol via a reverse aldol reaction into zingerone, which is less pungent and has a spicy-sweet aroma. When ginger is dried or mildly heated, gingerol undergoes a dehydration reaction forming shogaols, which are about twice as pungent as gingerol.NSF International ''Determination of Gingerols and Shogaols in Zingiber officinale rhizome and powdered extract by High-Performance Liquid Chromatography'' This explains why dried ginger is more pungent than fresh ginger. Ginger also contains gingerol, 0gingerol, and 2gingerol, collectively deemed g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shogaol
Shogaols are pungent constituents of ginger similar in chemical structure to gingerol. The most common of the group is shogaol. Like zingerone, it is produced when ginger is dried or cooked. Moreover, shogaol (and gingerol) are converted to other constituents when heat is applied over time, which is why ginger loses its spiciness as it is cooked. The name ''shogaol'' is derived from the Japanese name for ginger (生姜、''shōga''). Shogaol is rated 160,000 SHU on the Scoville scale. When compared to other pungent compounds, shogaol is moderately more pungent than piperine, but less than capsaicin. Shogaols group Shogaol, shogaol, 0shogaol, and 2shogaol (all found in ginger) together constitute the group shogaols. There also exist in ginger cultivars methylated shogaols: methyl shogaol and methyl shogaol, respectively. Shogaols are artifacts formed during storage or through excess heat, probably created by a dehydration reaction of the gingerols. The ratio of shoga ...

Phenol Antioxidants
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to wate ...
