Biochemistry.
- : a colorless, crystalline trisaccharide, C18H32O16⋅5H2O, with little or no sweetness, occurring in the sugar beet, cottonseed, etc., and breaking down to fructose, glucose, and galactose on hydrolysis.
Examples
It is a constituent of sucrose, of raffinose, and of the polysaccharide inulin, from which it may be obtained by hydrolysis.
The hydrolysis of raffinose presents several interesting possibilities.
Three trisaccharides which are non-reducing sugars are found in plants; namely, raffinose, gentianose, and melizitose.
Of the higher sugars raffinose is fermented by juice from bottom yeast, but more slowly than cane sugar or maltose.
