Carambola
Carambola, also known as star fruit, is the fruit of '' Averrhoa carambola'', a species of tree native to tropical Southeast Asia. The edible fruit has distinctive ridges running down its sides (usually 5–6). When cut in cross-section, it resembles a star, giving it the name of ''star fruit''. The entire fruit is edible, usually raw, and may be cooked or made into relishes, preserves, garnish, and juices. It is commonly consumed in Southeast Asia, South Asia, the South Pacific, Micronesia, parts of East Asia, the United States, parts of Latin America, and the Caribbean. The tree is cultivated throughout tropical areas of the world. Carambola fruits contain oxalic acid and the neurotoxin caramboxin. Consuming large quantities of the fruit, especially for individuals with some types of kidney disease, can result in serious adverse health effects. Origins and distribution The center of diversity and the original range of ''Averrhoa carambola'' is tropical Southeast Asi ...

Averrhoa Carambola
''Averrhoa carambola'' is a species of tree in the family Oxalidaceae native to tropical Southeast Asia; it has a number of common names, including carambola, star fruit and five-corner. It is a small tree or shrub that grows tall, with rose to red-purple flowers. The flowers are small and bell-shaped, with five petals that have whitish edges. The flowers are often produced year round under tropical conditions. The tree is cultivated in tropical and semitropical regions for Carambola, its edible fruits. Taxonomy The species in the genus ''Averrhoa'' along with the species in genus ''Sarcotheca'' are the only woody, tree-like plants belonging to the Oxalis family Oxalidaceae. The Oxalis family has nearly 900 species; most are herbaceous perennials or annuals native from tropical and semitropical locations, although a number also grow in other parts of the world. ''Averrhoa'' has sometimes been placed in the family Averrhoaceae. ''Averrhoa carambola'' is one of two species in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Averrhoa Carambola ARS K5735-7
''Averrhoa'' is a genus of trees in the family Oxalidaceae. It includes five species native to Java, the Maluku Islands, New Guinea, Sulawesi, and Vietnam. The genus is named after Averroes, a 12th-century astronomer and philosopher from Al-Andalus. Two species, the carambola and the bilimbi, are cultivated for their fruits. Species Five species are accepted. *''Averrhoa bilimbi ''Averrhoa bilimbi'' (commonly known as bilimbi, cucumber tree, or tree sorrel) is a fruit-bearing tree of the genus ''Averrhoa'', family (biology), family Oxalidaceae.

Caramboxin
Caramboxin (CBX) is a toxin found in star fruit (''Averrhoa carambola'') and the related bilimbi fruit ('' Averrhoa bilimbi''). Individuals with some types of kidney disease are susceptible to adverse neurological effects including intoxication, seizures and even death after eating star fruit and bilimbi fruit. In 2013, caramboxin was identified as the neurotoxin responsible for these effects. Caramboxin is a non-proteinogenic amino acid, with a chemical structure similar to the amino acid phenylalanine, but with extra hydroxyl, carboxyl and methoxy substituents, making it also a phenol, a benzoic acid, and a phenol ether. Caramboxin stimulates the glutamate receptors in neurons, being an agonist of both NMDA and AMPA glutamatergic ionotropic receptors with potent excitatory, convulsant, and neurodegenerative properties, resulting in symptoms of central nervous system disorder, including mental confusion, seizures, and status epilepticus.

Star Polygon
In geometry, a star polygon is a type of non-convex polygon. Regular star polygons have been studied in depth; while star polygons in general appear not to have been formally defined, Decagram (geometry)#Related figures, certain notable ones can arise through truncation operations on regular simple or star polygons. Branko Grünbaum identified two primary usages of this terminology by Johannes Kepler, one corresponding to the regular star polygons with List of self-intersecting polygons, intersecting edges that do not generate new vertices, and the other one to the isotoxal Concave polygon, concave simple polygons.Grünbaum & Shephard (1987). Tilings and Patterns. Section 2.5 Polygram (geometry), Polygrams include polygons like the pentagram, but also compound figures like the hexagram.

Center Of Diversity
A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. Centers of origin were first identified in 1924 by Nikolai Vavilov. Vavilov posited that the center of origin for a species or genus is the same as its ''center of diversity'', the geographic area where it has the highest genetic diversity, but this equivalence has been disputed by later scholars. Plants Locating the origin of crop plants is basic to plant breeding. This allows one to locate wild relatives, related species, and new genes (especially dominant genes, which may provide resistance to diseases). Knowledge of the origins of crop plants is important in order to avoid genetic erosion, the loss of germplasm due to the loss of ecotypes and landraces, loss of habitat (such as rainforests), and increased urbanization. Germplasm preservation is accomplished through gene banks (largely seed collections but now f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Islands
The Pacific islands are a group of islands in the Pacific Ocean. They are further categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term ''Pacific Islands'' may refer to one of several concepts: (1) those countries and islands with common Austronesian origins, (2) the islands once (or currently) colonized, (3) the geographical region of Oceania, or (4) any island located in the Pacific Ocean. This list of islands in the Pacific Ocean is organized by archipelago or political boundary. In order to keep this list of moderate size, the more complete lists for countries with large numbers of small or uninhabited islands have been hyperlinked.

Santol (fruit)
''Sandoricum koetjape'', the santol, sentul, setun or cotton fruit, is a tropical fruit native to maritime Southeast Asia. Origin and distribution The santol is native to Malesia and New Guinea. It has been introduced to Indochina, Sri Lanka, India, northern Australia, Mauritius, and Seychelles. It is commonly cultivated throughout these regions and the fruits are seasonally abundant in the local and international markets. Botanical description There are two varieties of santol fruit, previously considered two different species, the yellow variety and the red. The difference is in the color that the older leaves turn before falling. The red appears to be more common and the reddish leaves mixed with the green ones add to the distinction and attractiveness of the tree. The fruits are often the size, shape and slightly fuzzy texture of peaches, with a reddish tinge. Both types have a skin that may be a thin peel to a thicker rind, according to the variety. It is often edible an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
