Description
L(+)-Rhamnose namely 6-deoxy-L-mannose, also known as methyl pentose, is a naturally-occurring deoxy sugar that widely exists in plant polysaccharides, glycosides, plant gums, and polysaccharides on the surface of bacterial cells.
Its sweetness is about 33% of sucrose, which can be used as a sweetener, as well as in the production of flavors, spices, and edible.
