Lithium(I) ions are small but strongly hydrated and could interfere with Mg(II) biochemistry. However, the favored mode of action is interference with Ca(II) metabolism via inhibition of enzymes in the inositol phosphate pathways (470-472). Inositol phosphates are responsible for mobilizing Ca(II) inside cells in response to external stimnlii. Lithium also stimulates glutamate release presumably via activation of the AT-methyl-D-asparate receptor and leads to Ca(II) entry (473). The increased influx of intracellular Ca(II) may activate phospholipase C and stimulate accumulation of inositol 1,4,5-triphosphate (473). 

DNA from E.coil can be prevented by myo-inositol. Warner assumes that inositol may replace the hydrate water and stabilize the DNA structure like hydrate water228,233. ... 

It is a complex mixture of acetone-insoluble phosphatides that consists chiefly of phosphatidyl choline, phosphatidyl ethanolamine, and phosphatidyl inositol combined with various amounts of other substances such as triglycerides, fatty acids, and carbohydrates. Refined grades of Lecithin may contain any of these components in varying proportions and combinations depending on the type of fractionation used. In its oil-free form, the preponderance of triglycerides and fatty acids is removed and the product contains 90% or more of phosphatides representing ah or certain fractions of the total phosphatide complex. Edible diluents, such as cocoa butter and vegetable oils, often replace soybean oil to improve functional and flavor characteristics. Lecithin is only partially soluble in water, but it readily hydrates to form emulsions. The oil-free phosphatides are soluble in fatty acids, but they are practically insoluble in fixed oils. When ah phosphatide fractions are present, Lecithin is partially soluble in alcohol and practically insoluble in acetone.

Soybean lecithin is soluble in aliphatic and aromatic hydrocarbon solvents, partially soluble in ethyl alcohol (principally the inositol fraction), and practically insoluble in acetone (less than 0.003% weight/volume at 5°C) and in water (73). When mixed with water, soybean lecithin hydrates to a thick emulsion that can be thinned with water to almost any desired dilution. Acetone does dissolve readily in lecithin and will form a thin, uniform imbibition as long as the quantity of acetone is insufficient to precipitate the phospholipids. Lecithin is soluble in... 

The basic permanganate oxidation of conjugated 1,3-dienes is different from those reported for the 1,4-dienes above. Therefore, in the oxidation of cyclopentadiene and 1,3-cyclohexadiene (13) a mixture of five products 14-18 is obtained (equation 4) . In this reaction 14 and 16 are derived from the normal cis hydroxy la tions whereas 17 and 18 were said to be formed from 15 by hydration in what the authors term an epoxidic pathway. Formation of epoxy-diols under similar permanganate oxidations has been found for occidentalol (19), levopimaric acid (20) and a 1-chloro- or 1-bromo-l,3-diene (21) as an intermediate step in the synthesis of (+)-D-c/tfrc-3-inosose and (+)-D-c/r/ro-3-inositol (equation 5). The explanation for the epoxide formation in the oxidation of 1,3-dienes (13, 19-21) is not clear but may be connected to the fact that other additions of permanganate to dienes are possible beyond those commonly observed... 

Lecithin, a mixture of phosphatidyl choline, phosphaddyl ethanolamine, and phosphatidyl inositol, is used as a surfactant in many food, pharmaceutical, and cosmetic products. Lecithin is a product of soy bean oil degumming operations. It is obtained from the hexane extract of flaked soy beans which contains the seed oil and a portion of the phosphatides that are initially present in the soy bean membrane. The exhact is seated with water at 80 °C, and the phosphatides are hydrated rendering them oil insoluble which makes it easy to filler them from the oil. This oil insoluble fraction is termed cmde lecithin and consists of about 70% phosphatides and 30% oil. De-oiled lecithin is obtained by treating the cmde lecithin with acetone. Lecithin is insoluble in acetone and the oil is, and a separation into a 90 to 9r phosphatides fraction can be achieved quite readily. The prior...

Organic phosphorus compounds, primarily inositolhexaphosphates (probably more than 50% of all organic phosphates), occiu in soils. The parent cyclic polyol, inositol, exists in numerous stereoisomeric configurations, of which myo-, scyllo-, neo-, and cZZ-inositol have been isolated from soils as phosphate esters. The hexaphosphate of myoinositol (myo-IHP), phytic acid, occurs in plant tissues. It often occurs as phytin, the calcium magnesium salt. Esters of myo-IHP are readily adsorbed in acidic soil solution by clay minerals and finely divided hydrated oxides of iron and aluminum. Organic sulfur compounds present in soils probably occur primarily as amino acids—e.g., cysteine, cystine, and methionine.

Regioselective debenzoylation of nucleoside 2, 3 5-tri-O-benzoates using hydrazine hydrate has been reported. With 1 mol reagent in acetic acid-pyridine the 3 5-di-O-benzoyl derivative was produced when the bases were adenine, guanine, or indole, whereas with excess hydrazine hydrate in 1 1 chloroform-methanol, 98% of the 5-O-benzoyl derivative was produced (base = adenine or uracil). 3, 5-Di-O-benzoyl-2-deoxy-nucleosides gave a 90% yield of a 1 1 mixture of 3 - and 5-O-benzoyl nucleosides with 1 mol hydrazine hydrate in pyridine. Treatment of the mannose orthoacetate (5) with benzoyl chloride in pyridine gave 2,3,4,6-tetra-O-acetyl-a-D-mannopyranosyl chloride and ethylbenzoate, whereas the related orthoester of mu co-inositol (6) gave 66% of the correspond-... 

A range of mono- and di-anhydro-inositols have been prepared from the isomeric 3,6-dibromocyclohexadienemono-epoxides (6) by conventional transformations via the corresponding anhydroconduritols (7). Another paper reports the synthesis of all the 1,2,3,4- and 1,2,4,5-dianhydro-inositols from inositol disulphonates using sodium methoxide. The hydration of three inososes...
