(biochemistry)
A sugar whose cyclic or ring structure resembles that of furan.

Furanose

 

a ring-shaped monosaccharide containing a five-member furan ring. Unlike the six-member (pyranose) form, fu-ranoses are less stable and for most monosaccharides exist only in aqueous solutions and in substantially smaller quantities than pyranoses. The tendency to form a furanose ring is clearly visible, for example, in fructose, which in furanose form is also a component of many oligosaccharides and polysaccharides, such as inu-lin. Most of the monosaccharides in glycosides, oligosaccharides, and polysaccharides have the pyranose form. Glycosides in which the sugar part is represented by furanoses are called furanosides.

However, these results directly indicate that the degradation of CH in the aromatic skeletal region due to lignin and the degradation of CH in the furanose (or pyranose) region due to hemicellulose contributed to the yellowing of the wood samples.
The term "Locked Nucleic Acids" was coined by Exiqon to emphasize that the usual conformational freedom of the furanose ring in standard nucleosides is restricted in LNA(TM) due to a methylene linker connecting the 2'-O position to the 4'-C position.
