reducing sugar
Aldose or ketose
A reducing sugar is any sugar that can act as a reducing agent in chemical reactions, donating electrons to other molecules.
This category includes glucose, fructose, lactose, and maltose—sugars with a free aldehyde or ketone group that can reduce other compounds.
The term matters primarily in biochemistry and food science, where reducing sugars are tested for in urine samples and play key roles in browning reactions during cooking.
