Translation of "Gentiobiose" in German

The stereoisomeric disaccharides cellobiose, gentiobiose or isomaltose can also be used instead of maltose.

Instead of maltose it is also possible to use the stereoisomeric disaccharides cellobiose, gentiobiose or isomaltose.

The trisaccharides (C18 H32 O16), raffinose, which is concentrated in molasses, and gentianose and melecitose, the tetrasaccharide stachyose found in the seeds of many leguminous plants and the pentasaccharide verbascose do not reduce Fehling's solution and are only accessible to a-C-methylolation according to the invention if they are first completely or partly hydrolyzed, for example in a one-pot process, e.g. as described in Example 12, variation c, into galactose, glucose and fructose or fructose and gentiobiose, or glucose and fructose or galactose, glucose and fructose. EXAMPLE 15

As starting materials it is possible to employ, in addition to glucose, especially all other disaccharides, oligosaccharides or polysaccharides which are composed solely of glucose or anhydroglycose structural units, for example maltose, cellobiose, trehalose, isomaltose, gentiobiose, maltotriose, cellotriose etc. through cellulose, starch, glycogen and the like.

The trisaccharides (C18 H32 O16), raffinose, which is concentrated in molasses, and gentianose and melecitose, the tetrasaccharide stachyose found in the seeds of many leguminous plants and the pentasaccharide verbascose do not reduce Fehling's solution and are only accessible to a-C-methylolation according to the invention if they are first completely or partly hydrolyzed, for example in a one-pot process, e.g. as described in Example 12, variation c, into galactose, glucose and fructose or fructose and gentiobiose, or glucose and fructose or galactose, glucose and fructose.

Preferred glycoside components are monosaccharides, e.g., D-glucose, and also D-galactose, D-glucuronic acid, D-galacturonic acid, D-xylose, D-apiose, L-rhamnose and L-arabinose, and disaccharides, e.g., rhamnosylglucoses, particularly preferably rutinose and neohesperidose, and also, for example, rungiose, robinobiose, sophorose, gentiobiose, apiobiose, vicianose, sambubiose, primverose or latyrose.

By 1928, he had deduced and confirmed the structures of maltose, cellobiose, lactose, gentiobiose, melibiose, gentianose, raffinose, as well as the glucoside ring tautomeric structure of aldose sugars.

Suitable disaccharides are, for example, cellobiose, gentiobiose, isomaltose, isomaltulose, lactose, lactulose, laminaribiose, maltose, maltulose, melibiose, neohesperidose, neotrehalose, nigerose, rutinose, sambubiose, sophorose, saccharose, and trehalose.

Very particularly preferably, Q is derived from a compound chosen from sorbitol, 1,5-anhydrosorbitol, 1,4-anhydrosorbitol, inositol, xylitol, mannitol, gluconolactone, glucuronic acid, 1,2,6-hexanetriol, hydroxyethylsorbitol, phytantriol, hydroxypropylphytantriol, lactitol, maltitol, pentaerythritol, polyglycerol-3, glucose, fructose, galactose, ribose, xylose, mannose, sucrose, cellobiose, gentiobiose, isomaltose, lactose, lactulose, maltose, maltutose, melibiose, trehalose, nigerose, palatinose, rutinose, arabinose.

In addition to a-glucosyl fluoride, suitable starting compounds are also the a-fluorides of other reducing monosaccharides or oligosaccharides--this term embracing 2-4 structural units--such as the a-fluorides of galactose, mannose, gulose, talose, allose, altrose and the like, including the a-fluorides belonging to the series of C5 -aldoses, such as xylose, ribose and the like, or, in the case of the oligosaccharides, especially the a-fluorides of the disaccharides, such as lactose, maltose, cellobiose, gentiobiose and the like, or higher saccharides, such as maltotriose, raffinose, maltotetraose and stachyose.

In this case, preferred hair treatment agents according to the invention are characterized in that they include as care substance—based on their weight—0.01 to 5 wt. %, preferably 0.05 to 4.5 wt. %, particularly preferably 0.1 to 4 wt. %, more preferably 0.5 to 3.5 wt. % and in particular 0.75 to 2.5 wt. % carbohydrate(s), selected from monosaccharides, disaccharides and/or oligosaccharides, wherein preferred carbohydrates are selected from monosaccharides, in particular D-ribose and/or D-xylose and/or L-arabinose and/or D-glucose and/or D-mannose and/or D-galactose and/or D-fructose and/or sorbose and/or L-fucose and/or L-rhamnose as well as disaccharides, in particular sucrose and/or maltose and/or lactose and/or trehalose and/or cellobiose and/or gentiobiose and/or isomaltose.

The disaccharides used are preferably selected from lactose, maltose, sucrose, trehalose, turanose, gentiobiose, melibiose and cellobiose.

In principle, however, disaccharides, such as saccharose (or also known as sucrose), lactose, trehalose, maltose, cellobiose, gentiobiose or melibiose, are also suitable.

Examples of oligosaccharides suitable as starting materials are the disaccharides, for instance sucrose, isomaltose, gentiobiose, melibiose, trehalose, mannopyranosylmannopyranose, maltose, lactose, trehalose and cellobiose, and trisaccharides, for instance raffinose.

The polyhydroxyalkyl radical Z is derived from monosaccharides such aserythrose, threose, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose, talose or fluctose or derivatives thereof such as glucuronic acid or deoxyribose or oligosaccharides and especially disaccharides such as saccharose, lactose, trehalose, maltose, cellobiose or gentiobiose, and also from trisaccharides such as raffinose. Also suitable are all commercial starch degradation products such as glucose syrup or dextrins, eg, maltodextrins.
