  Glucoside - Wikipedia, the free encyclopedia
A glucoside is a glycoside that is derived from glucose.
Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes.
Mention may also be made of indican, the glucoside of the indigo plant; this is hydrolysed by the indigo ferment, indimulsiri, to indoxyl and indiglucin.

 GLUCOSIDE - LoveToKnow Article on GLUCOSIDE
Although glucose is the commonest sugar present in glucosides, many are known which yield rhamnose or iso-dulcite; these may be termed pentosides.
The simplest glucosides are the alkyl esters which E. Fischer (Ber., 28, pp.
By acting with these enzymes on the natural glucosides, it is found that the majority are of the 8-form; eg.

 Epipodophyllotoxinquinone glucoside derivatives, method of production and use - Patent 4609644   (Site not responding. Last check: 2007-10-21)
Of particular interest are the 4'-demethylepipodophyllotoxin glucoside derivatives having the structural formula (II): ##STR3## in which R.sub.1 is hydrogen, and R.sub.2 is an alkyl; alkenyl; cycloalkyl; 2-furyl; 2-thienyl; aryl; aralkyl; and aralkenyl, wherein the aromatic ring may optionally be substituted, preferably by one or more of hydroxy, alkyl, alkoxy, nitro, or halogen radicals.
However, the glucoside derivatives, in spite of their anti-cancer effectiveness, have not proven to be completely satisfactory because the compounds are relatively insoluble in water, the compound not having sufficient solubility to permit administration as aqueous solutions.
Accordingly, the present inventor, in an effort to circumvent the undesirable side effects of the solvents used to solubilize the prior art glucoside derivatives of epipodophyllotoxin, has invented new compounds which are derivatives of the prior art compounds and which are further characterized by being water soluble.

 Polyol fragrance fixatives - Patent 4264478
A typical method used, is to react the aklylene oxide with methyl glucoside in the presence of an alkaline catalyst (such as potassium hydroxide) at a temperature of 140.degree.-160.degree.
The methyl glucoside polyols of the present invention are added to fragranced compositions in amounts from about 0.5% to about 5% by weight based upon total alcoholic, aqueous or hydroalcoholic content of said composition to produce an acceptable fragrance fixation effect.
In the material with 2.0% 20 mole propoxylate of methyl glucoside, 100% of the panelists judged the methyl glucoside polyol treated material to be less pungent than and therefore preferred to the untreated SD 40 alcohol.

 J. Biochem. 130, pp. 671-677 (2001)[body text]
In spite of the described advantages of octyl glucoside as a detergent, there are, however, some other reports that emphasize the inability of octyl glucoside to allow solubilized membrane proteins to be prepared in an active form (17).
The binding of ANS to GDH in the presence of various concentrations of octyl glucoside was investigated by spectrofluorimetry, as illustrated in Fig.
In conclusion, it appears that octyl glucoside molecules that bind to GDH lower the dielectric constant of water where the concealed or semi-concealed hydrophobic clusters of amino acid side chains are located, allowing them to become exposed partly to the solvent, resulting in an increase in the surface hydrophobicity of GDH.

 Nutrition Journal | Full text | In vitro digestion and lactase treatment influence uptake of quercetin and quercetin ...
It has been estimated that quercetin glucoside bioavailability may be as high as 80% in humans and quercetin bioavailability may range from 35–53% [26,33].
The deglycosylation of the quercetin glucoside would result in a higher concentration of aglycone at the apical enterocyte membrane and potentially increase the rate of absorption [35].
Since lactase is an important enzyme in the metabolism and subsequent absorption of quercetin glucosides, lactose intolerant individuals may have a reduced capability to hydrolyze quercetin glucoside for further absorption across the small intestinal wall.

The principal molecule is simmondsin [2-(cyanomethylene)-3-hydroxy-4,5-dmethoxycyclohexyl beta-D glucoside] (up to 7 % by weight of defatted jojoba meal).
As simmondsin induces food intake depression and emaciation, it was thought to be toxic.
The aim of our research on simmondsin and defatted jojoba meal was to unravel the mechanism of action of simmondsin, to study possible toxic influences and to investigate its potential as a food intake depressant.

Even though the liver is the most important site of MPA glucuronidation, extrahepatic tissues particularly the kidney may play a significant role in the overall biotransformation of MPA in man. Only kidney microsomes formed a putative acyl glucoside of MPA.

Octyl Glucoside Extracts GTP-Binding Regulatory Proteins from Rat Brain "Synaptoneurosomes" as Large, Polydisperse Structures Devoid of {beta}{gamma} Complexes and Sensitive to Disaggregation of Guanine Nucleotides -- Nakamura and Rodbell 87 (16): 6413 -- Proceedings of the National Academy of Sciences
In this study we extracted the proteins from rat brain "synaptoneurosomes" using the neutral detergent 1-octyl ß-D-glucopyranoside (octyl glucoside).
These findings suggest that the transducing GTP-binding proteins in synaptoneurosomes exist as polydisperse, possibly multimer, structures of various size that are stable in octyl glucoside but destroyed by cholate.

This study combined an in vitro digestion, a lactase treatment and the Caco-2 cell model to examine quercetin and quercetin glucoside uptake from shallot and apple homogenates.
Combining the digestion, the lactase treatment and the Caco-2 cell culture model may provide a reliable in vitro model for examining flavonoid glucoside bioavailability from foods.
