L-chiro-inositol
The chemical compound 1L-''chiro''-inositol (often called L-''chiro''-inositol or LCI) is one of the nine stereoisomers of cyclohexane-1,2,3,4,5,6-hexol, with formula , the generic "inositol". Its molecule has a ring of six carbon atoms, each bonded to a hydrogen atom and a hydroxyl group (–OH). Imagining the ring is horizontal, the hydroxyls on carbons 1, 2, and 4, in clockwise order are above the respective hydrogens, while the other three are below them. The compound occurs in the human body and other organisms, together with its enantiomer (mirror image isomer) 1D-''chiro''-inositol (DCI), but at a much lower concentration than the main isomer ''myo''-inositol. Structure L-''chiro''-inositol crystallizes in the monoclinic system, group P21, with cell dimensions ''a'' = 686.7 pm, ''b'' = 913.3 pm, ''c'' = 621.7 pm (±0.004 pm) angle ''β'' = 106.59 ° (± 0.04°), molecular count ''Z'' = 2. The molecule has the expected chair conformation, with puckering parameters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclohexane-1,2,3,4,5,6-hexol
Cyclohexane-1,2,3,4,5,6-hexol is a family of chemical compounds with elemental formula, formula , whose molecule consists of a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl group (–OH). There are nine stereoisomers, that differ by the position of the hydroxyl groups relative to the mean plane of the ring. All these compounds are sometimes called inositol, although this name (especially in biochemistry and related sciences) most often refers to a particular isomer, inositol, ''myo''-inositol, which has many important physiological roles and medical uses. These compounds are classified as sugars, specifically carbocycle, carbocyclic sugars or sugar alcohols, to distinguish them from the more common aldoses like glucose. They generally have sweet taste. These compounds form several esters with biochemical and industrial importance, such as phytic acid and phosphatidylinositol phosphate (other), phosphatidylinositol phosphate, Isomers and s ...

Inositol
In biochemistry, medicine, and related sciences, inositol generally refers to ''myo''-inositol (formerly ''meso''-inositol), the most important stereoisomer of the chemical compound cyclohexane-1,2,3,4,5,6-hexol. Its elemental formula, formula is ; the molecule has a ring of six carbon atoms, each with a hydrogen atom and a hydroxyl group (–OH). In ''myo''-inositol, two of the hydroxyls, neither adjacent nor opposite, lie above the respective hydrogens relative to the mean plane of the ring. The compound is a carbohydrate, specifically a sugar alcohol (as distinct from aldoses like glucose) with half the sweetness of sucrose (table sugar). It is one of the most ancient components of living beings with multiple functions in eukaryotes, including structural lipids and secondary messengers. A human kidney makes about two grams per day from glucose, but other tissues synthesize it too. The highest concentration is in the brain, where it plays an important role in making other neurot ...

Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken or new bonds formed or both. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, usin ...

Quebrachitol
Quebrachitol is a naturally occurring optically active cyclitol, a cyclic polyol. It can be found in '' Allophylus edulis'' and in the serum left after the coagulation of the ''Hevea brasiliensis'' latex in the operation of rubber tapping. It is also found in ''Cannabis sativa'', in '' Paullinia pinnata'' and in seabuckthorn. It was first isolated by Tanret in 1887 from the bark of '' Aspidosperma quebracho''. The substance was tested as a sweetening agent for diabetics in 1933. It shows a sweetening property half of that of sucrose but induces colic or diarrhoea Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration d ... at concentration used to render the food palatable.

Syringodium Filiforme
''Syringodium filiforme'', commonly known as manatee grass, is a species of marine seagrass. It forms meadows in shallow sandy or muddy locations in the Caribbean Sea and the Gulf of Mexico, and is also found in the Bahamas and Bermuda. It occurs to a depth of about , and even deeper where water is very clear. Climate change Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in ... Manatee seagrasses are a flowering plant that thrives in shallow saltwater around the coast of Florida. Worldwide Manatee seagrass is experiencing global decline due to ever changing events in their environment. These descendants of terrestrial plants that were able to survive over 65 million years of evolution are now facing being wiped from the planet due to climate change and other anthropogenic factors. ...

Ester
In chemistry, an ester is a compound derived from an acid (either organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group () of that acid is replaced by an organyl group (R). These compounds contain a distinctive functional group. Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well. According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. Lactones are cyclic carboxylic esters; naturally occurring lactones are mainly 5- and 6-membered ring lactones. Lactones contribute to the aroma of fruits, butter, cheese, vegetables like celery and other foods. Esters can be formed from oxoacids (e.g. esters of acetic acid, carbonic acid ...
