Sesamum Alatum
''Sesamum alatum'' is a species of flowering plant in the Pedaliaceae. It is in the same genus as sesame. In English it is called winged-seed sesame. Its native range spans from Western Sahara to Egypt and south to KwaZulu-Natal in South Africa. Etymology The scientific name for the genus ''Sesamum'' derives from Latin ''sesamum'' and Greek ''sēsamon''; which in return derive from ancient Semitic languages, akin to Akkadian ''šamaššamu''. The roots of the words generally referred to "oil" or "liquid fat". The scientific name for the species ''alatum'' comes from the neuter form of Latin ''alatus'' meaning "winged". Description It is an annual erect herb, reaching heights of 50 to 150 cm. It has heteromorphic leaves deeply divided into narrow, linear-lanceolate lobes; the upper leaves are simple, with the exception of some mucilage glands with an entire margin. Its flowers measure 3.5 cm in diameter and are reddish pink with darker lines in the lower lobe o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kruger National Park
Kruger National Park () is a national park in South Africa covering an area of in the provinces of Limpopo and Mpumalanga in the country's northeast. It extends from north to south and from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926. It is part of Kruger to Canyons Biosphere, an area designated as a biosphere reserve. History Conservation Pre-Game Reserve (1867-1898) A Game Commission was established in 1891 with J.M. Malan of Rustenberg as chairperson which resulted in the establishment of the game law of 1891 It must be noted that there were already individual farmers as far back as 1867 who published notices in the ''Staatscourant'' to prohibit hunting and so try preserve the game on their own land. In total 200 owners protected game on about 300 farms between 1867 and 1881 in this manner. One o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chadian Arabic
Chadian Arabic (), also known as Shuwa Arabic, Western Sudanic Arabic, or West Sudanic Arabic (WSA), is a variety of Arabic and the first language of 1.9 million people in Chad, both town dwellers and Baggara, nomadic cattle herders. Most of its speakers live in central and southern Chad. Its range is an east-to-west oval in the Sahel. Nearly all of this territory is within Chad and Sudan. It is also spoken elsewhere in the vicinity of Lake Chad in the countries of Cameroon, Nigeria and Niger. Finally, it is spoken in slivers of the Central African Republic. In addition, this language serves as a lingua franca in much of the region. In most of its range, it is one of several local languages and often not among the major ones. Naming and classification This language does not have a native name shared by all its speakers, beyond "Arabic". It arose as the native language of nomadic cattle herders (''baggāra'', Standard Arabic ''baqqāra'' , means 'cattlemen', from ''baqar''). In 1 ...

Sesame
Sesame (; ''Sesamum indicum'') is a plant in the genus '' Sesamum'', also called benne. Numerous wild relatives occur in Africa and a smaller number in India. It is widely naturalized in tropical regions around the world and is cultivated for its edible seeds, which grow in pods. World production in 2018 was , with Sudan, Myanmar, and India as the largest producers. Sesame seed is one of the oldest oilseed crops known, domesticated well over 3,000 years ago. ''Sesamum'' has many other species, most being wild and native to sub-Saharan Africa. ''S. indicum,'' the cultivated type, originated in India. It tolerates drought conditions well, growing where other crops fail. Sesame has one of the highest oil contents of any seed. With a rich, nutty flavor, it is a common ingredient in cuisines around the world. Like other foods, it can trigger allergic reactions in some people and is one of the nine most common allergens outlined by the Food and Drug Administration. Etymology Th ...

Linoleic Acid
Linoleic acid (LA) is an organic compound with the formula . Both alkene groups () are ''cis''. It is a fatty acid sometimes denoted 18:2 (n−6) or 18:2 ''cis''-9,12. A linoleate is a salt or ester of this acid. Linoleic acid is a polyunsaturated, omega−6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents. It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid. It is one of two essential fatty acids for humans, who must obtain it through their diet, and the most essential, because the body uses it as a base to make the others. The word "linoleic" derives , reflecting the fact that it was first isolated from linseed oil. History In 1844, F. Sacc, working at the laboratory of Justus von Liebig Justus ''Freiherr'' von Liebig (12 May 1803 – 18 April 1873) was a Germans, German scientist who made major contributions to the theory, practice, and pedagogy of che ...

Palmitic Acid
Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms.Gunstone, F. D., John L. Harwood, and Albert J. Dijkstra. The Lipid Handbook, 3rd ed. Boca Raton: CRC Press, 2007. , Its chemical formula is , and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0. It is a major component of palm oil from the fruit of '' Elaeis guineensis'' ( oil palms), making up to 44% of total fats. Meats, cheeses, butter, and other dairy products also contain palmitic acid, amounting to 50–60% of total fats. Palmitates are the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4). Major sources of C16:0 are palm oil, palm kernel oil, coconut oil, and milk fat. Occurrence and production Palmitic acid was discovered by saponification of palm oil, which process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oleic Acid
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 ''cis''-9, and a main product of Δ9-desaturase. It has the formula . The name derives from the Latin word '' oleum'', which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. It is a common component of oils, and thus occurs in many types of food, as well as in soap. Occurrence Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (trigl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mucilage
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Cacti (and other succulents) and flax seeds are especially rich sources of mucilage. Occurrence Exopolysaccharides are the most stabilising factor for microaggregates and are widely distributed in soils. Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occu ...
