Description
Introduction of L-Rhamnose
Rhamnose, also known as 6-deoxy-Lmannose, is an organic compound with a molecular formula of C6H12O5. It is a substance widely present in plant polysaccharides, glycosides, plant gums, and bacterial polysaccharides. Its sweetness is 33% of sucrose, which can be used to determine the permeability of intestinal tract, as a sweetener, and also can be used to produce essence and spices. It is edible.
Widely distributed in bacteria and plants, polysaccharides or lipopolysaccharides composed of rhamnose are present on the cell surface in bacteria. This sugar chain structure often becomes an antigen-specific factor. In addition to being present in the form of free sugars in the leaves and flowers of Rhus toxicodendron, it is also distributed in the form of various glycosides such as rutin and polysaccharides such as arabic gum.
Rhamnose can be used to determine the permeability of intestinal tract, can be used as a sweetener, can also be used to produce essence and spices, and can be eaten.
1.It can be used to test the permeability of intestinal tract.
2.It is a naturally occurring sugar, and can be used as sweetener.
3.It can be used in the production of flavoring.
