Optionally, Rhamnose and Xylose are present in the seaweed extract in amounts in a ratio of approximately 12 Rhamnose to 1 Xylose and 8 Rhamnose to 1 Xylose.
Preferably, the Rhamnose (algopolysaccharide) is sulfinated.
The substrate is exemplified with rhamnose, fucose, pectin with a high percentage of rhamnose, and fucodian having a high percentage of fucose.
Optionally, a rhamnose fraction may also be recovered.
Said other monosaccharides are typically selected from galactose and rhamnose.
The polysaccharide according to the present invention preferably has at least rhamnose as a constituent sugar.
The invention relates to a method for splitting rutinosides in order to obtain rhamnose and/or the corresponding aglycones.
For achieve thus purpose, an angiogenesis inhibitor which contains a sulfated polysaccharide having rhamnose as the main constituting monosaccharide or its salt is provided.
A molecule of natural origin, rhamnose originates from a plant sugar.
The invention provides a process for preparing L-rhamnose by hydrolysing glycosidic bonds in a glycoside having rhamnose in a terminal position by heating in an aqueous solution of an organic carboxylic acid at a pH between 1 and 3.
4.L-rhamnose is used for antibiosis and antineoplastic activity.
The L-rhamnose isomerase is derived from a strain (IPOD FERM BP-08593) belonging to Pseudomonas stutzerii.
More particularly the present invention provides a genetic sequence encoding UDP rhamnose: anthocyanidin-3-glucoside rhamnosyltransferase (3RT).
The reducing sugar is preferably selected from the group containing rhamnose, fucose and glucose.
Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose).
Adding to that it is mostly composed of rhamnose and glycogen.
Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose).
Rhamnose acts as a receiver and sends signals to the cells.
Small amounts of rhamnose and of glucose (derived from traces of starch and/or cellulose) may also be present
A DNA encoding the following protein (a) or (b).
