60 results about "Rare sugar" patented technology

A rare sugar is a sugar that occurs in very small quantities in nature. Typically they occur in amounts too small to allow for economic separation from their underlying natural source and are typically made through biological processes such as fermentation or enzyme conversion to create the identical compound.

Application of L-rhamnulose-1-phosphate aldolase in catalytic synthesis of rare sugars

The invention discloses application of L-rhamnulose-1-phosphate aldolase in catalytic synthesis of rare sugars. In order to avoid the direct use of DHAP (dihydroxyacetone phosphate) and greatly decrease the synthesis cost of rare sugars, a 'single kettle with four enzymes' strategy is adopted, the L-rhamnulose-1-phosphate aldolase derived from Thermotoga maritima MSB8 is used for synthesizing a series of rare sugars such as D-allulose, D- sorbose, L-fructose and L-tagatose. Experiments show that the aldolase has good thermal stability and can be used for highly selectively synthesizing D-allulose having important application value while D-glyceraldehyde is used as a receptor.
