Why is xylose a reducing sugar?

Reducing sugars are sugars that are able to act as reducing agents. This is because they have an available ketone or aldehyde group. In general, all monosaccharides (including xylose) are reducing sugars. read more

Xylose is also the first saccharide added to the serine or threonine in the proteoglycan type O-glycosylation, and, so, it is the first saccharide in biosynthetic pathways of most anionic polysaccharides such as heparan sulfate and chondroitin sulfate. read more

A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. All monosaccharides are reducing sugars, along with some disaccharides, oligosaccharides, and polysaccharides. read more
