Pinitol
Pinitol is a cyclitol, a cyclic polyol. It is a known anti-diabetic agent isolated from ''Sutherlandia frutescens'' leaves. Gall plant tannins can be differentiated by their content of pinitol. It was first identified in the sugar pine (''Pinus lambertiana''). It is also found in other plants, such as in the pods of the carob tree. Certain variants of the bacteria ''Pseudomonas putida'' have been used in organic synthesis, the first example being the oxidation of benzene, employed by Steven Ley in the synthesis of (±)-pinitol.

Cyclitol
In organic chemistry, a cyclitol is a cycloalkane containing at least three hydroxyl, each attached to a different ring carbon atom. The general formula for an unsubstituted cyclitol is or where 3 ≤ ''x'' ≤ ''n''. The name is also used for compounds that can be viewed as result of substituting various functional groups for the hydrogen atoms in such a molecule, as well as similar molecules with one or more double bonds in the ring. Cyclitols and their derivatives are some of the compatible solutes which are formed in a plant as a response to salt or water stress. Some cyclitols (e.g. quinic or shikimic acid) are parts of hydrolysable tannins. Isomerism and nomenclature Unsubstituted cyclitols with the same ring size and number of hydroxyls may exist in several structural isomers, depending on the position of the hydroxyls along the ring. For example, cyclohexanetriol exists in three distinct isomers (1,2,3-, 1,2,4-, and 1,3,5-). Furthermore, the hydrogen and the hydroxyl ...

Digalactoside
A galactoside is a glycoside containing galactose. The H of the OH group on carbon-1 of galactose is replaced by an organic moiety. Depending on whether the glycosidic bond lies "above" or "below" the plane of the galactose molecule, galactosides are classified as α-galactosides or β-galactosides. A β-galactoside is a type of galactoside in which the glycosidic bond lies above the plane of the galactose Galactose (, '' galacto-'' + ''-ose'', "milk sugar"), sometimes abbreviated Gal, is a monosaccharide sugar that is about as sweet as glucose, and about 65% as sweet as sucrose. It is an aldohexose and a C-4 epimer of glucose. A galactose molecu ... residue. The most commonly recognized and used β-galactoside in biochemistry is lactose. However, other chemicals, such as ONPG, are known, but these are typically synthesized for biochemical assays. Galactosides play significant roles in metabolic processes of many organisms and are hydrolyzed by a class of enzymes called g ...

Jesús Jiménez Barbero
Jesús Jiménez Barbero (born 1960, in Madrid) is a Spanish scientist who has contributed to the advance of glycoscience by unraveling the conformational properties of carbohydrates and analogues and the molecular basis of their interactions with proteins, using a multidisciplinary approach that employs carbohydrate synthesis, molecular biology, molecular modelling and Nuclear Magnetic Resonance (NMR) spectroscopy. Academic career He studied chemistry at the Universidad Autonoma de Madrid where he obtained his PhD in 1987. He continued post-doctoral research at National Institute for Medical Research at Mill Hill. From 1990 to 1992, he was visiting scientist at Carnegie Mellon University (Pittsburgh Pittsburgh ( ) is a city in the Commonwealth of Pennsylvania, United States, and the county seat of Allegheny County.

Chickpea
The chickpea or chick pea (''Cicer arietinum'') is an annual legume of the family Fabaceae, subfamily Faboideae. Its different types are variously known as gram" or Bengal gram, garbanzo or garbanzo bean, or Egyptian pea. Chickpea seeds are high in protein. It is one of the earliest cultivated legumes, and 9500-year-old remains have been found in the Middle East. The chickpea is a key ingredient in Mediterranean and Middle Eastern cuisines, used in hummus, and, when ground into flour, falafel. It also is important in Indian cuisine, used in salads, soups and stews, and curry, in chana masala, and in other meal products like channa. In 2019, India was responsible for 70% of global chickpea production. Etymology The name "chickpea," earlier "chiche pease," is modelled on Middle French ', where ''chiche'' comes from Latin '. "Chich" was used by itself in English from the 14th to the 18th centuries.''Oxford English Dictionary'', 3rd edition, December 201''s.v.''/ref> The word ', fr ...

Lentil
The lentil (''Lens culinaris'' or ''Lens esculenta'') is an edible legume. It is an annual plant known for its lens-shaped seeds. It is about tall, and the seeds grow in pods, usually with two seeds in each. As a food crop, the largest producer is Canada, producing 45% of the world’s total lentils. In cuisines of the Indian subcontinent, where lentils are a staple, split lentils (often with their hulls removed) known as dal are often cooked into a thick curry/gravy that is usually eaten with rice or '' rotis''. Botanical description Name Many different names in different parts of the world are used for the crop lentil. The first use of the word ''lens'' to designate a specific genus was in the 16th century by the botanist Tournefort. The word "lens" for the lentil is of classical Roman/Latin origin: McGee points out that a prominent Roman family took the name " Lentulus", just as the family name "Cicero" was derived from the chickpea, '' Cicer arietinum'', or ...

White Lupin
''Lupinus albus'', commonly known as the white lupin or field lupine, is a member of the genus ''Lupinus'' in the family Fabaceae. It is a traditional pulse cultivated in the Mediterranean region. Description The white lupin is annual, more or less pubescent plant, 30 to 120 cm high, has a wide distribution in the Mediterranean region. White lupine is widely spread as wild plants throughout the southern Balkans, the Italian mainland region of Apulia, the islands of Sicily, Corsica, and Sardinia, and the Aegean Sea, as well as in Lebanon, Israel, Palestine, and western Anatolia. It occurs in meadows, pastures, and grassy slopes, predominantly on sandy and acid soils. It is cultivated over all the Mediterranean region and also in Egypt, Sudan, Ethiopia, Syria, Central and Western Europe, USA and South America, Tropical and Southern Africa, Russia, and Ukraine. The ancient culture of white lupin under the local name "hanchcoly" was practiced until recently in Western Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
