White to off-white crystalline powder or crystals | [Uses]
L-Sorbose is used as a starting reagent for the commercial biosynthesis of ascorbic acid (vitamin C). | [Uses]
In the manufacture of vitamin C (accounts for nearly 1000 tons of ascorbic acid produced every year). For conversion of L-sorbose to 2-keto-L-gulonic acid see Reichstein, Grüssner, Helv. Chim. Acta 17, 311 (1934). | [Uses]
L-Sorbose is a low molecular weight naturally occurring monosaccharide carbohydrate molecule. It has sweetness that is nearly equivalent to that of sucrose. This is a labeled analog. | [Definition]
ChEBI: Keto-L-sorbose is a L-sorbose. It is an enantiomer of a keto-D-sorbose. | [Biochem/physiol Actions]
The L enatiomer of sorbose, a ketohexose monosaccharide. | [Synthesis]
The target compounds were synthesized from D-fructose by the following steps: 2-hydroxypropanoic acid, D-witch hazel sugar, (3S,4R,5S)-1,3,4,5,6-pentahydroxyhexan-2-one, (3S,4S,5R)-1,3,4,5,6-pentahydroxyhexan-2-one, (3R,4R,5R)-1,3,4,5,6-pentahydroxyhexan-2-one, 1 ,3-dihydroxyacetone and DL-glyceraldehyde. This was done as follows: the D-fructose was reacted with MoO3 in water at 100 °C for 4 h. After completion of the reaction, the fructose-containing grades were separated by appropriate methods. Analysis using 1H NMR spectroscopy (shown in Fig. 8) confirmed the presence of sorbose in the separated grades. | [storage]
