sorbose การใช้

• L-Sorbose is the configuration of the naturally occurring sugar.
• The commercial production of vitamin C ( ascorbic acid ) often begins with sorbose.
• For example sorbose-sugar; sorbitol-sugar alcohol, and so on.
• "' Sorbose "'is a ketose belonging to the group of sugars known as monosaccharides.
• Flies which fed upon sorbitol as a major food subtrate excreted bacteria which were able to synthesize sorbose from sorbitol.
• This used an intermediate step of creating sorbose using an ingenious bacterial fermentation method discovered by a French researcher, Gabriel Bertrand.
• In modern methods however, sorbose is directly oxidized with a platinum catalyst ( developed by Kurt Heyns ( 1908 2005 ) in 1942 ).
• Using the bacteria, within a few days, it was possible to create 50 grams of sorbose using this method, and it was then easy to synthesise ascorbic acid from this.
• Despite concern about using the wild strain of bacteria for fermentation-production of sorbose, the process was superior to a rival method of Szent-Gyorgyi which isolated Vitamin C from capsicum.
• A second genetically modified microbe species, such as mutant " Erwinia ", among others, oxidises sorbose into 2-ketogluconic acid ( 2-KGA ), which can then undergo ring-closing lactonization via dehydration.
• No acid is produced from adonitol, arabinose, arbutin, cellobiose, dulcitol, fucose, galactose, inositol, inulin, lactose, maltose, mannitol, mannose, melezitose, melibiose, raffinose, rhamnose, ribose, salicin, sorbose, or tagatose.
