Glucose is the most abundant monosaccharide in nature and the primary energy source for most living organisms. The chemical properties that make this possible are determined by the specific functional groups of glucose, which include both aldehyde and multiple hydroxyl groups.

Monosaccharides, the simplest form of sugar, are categorized by the functional group they contain, which determines their chemical properties. Sugars with an aldehyde group ($$-CHO$$) on their terminal carbon are known as aldoses and include many of the most important carbohydrates found in nature.

In biochemistry, a sugar's ability to act as a reducing agent is a fundamental property, with over 1% of the monomers in aqueous solutions existing in their reactive open-chain form. Glyceraldehyde, a simple three-carbon monosaccharide, is a classic example of a reducing sugar due to its chemical structure. This article explores why glyceraldehyde exhibits these properties and the chemical basis for its classification.

Every monosaccharide is a reducing sugar. This fundamental chemical property, stemming from the presence of a free aldehyde or ketone group, means that all monosaccharides, from glucose to fructose, can donate electrons and reduce other compounds.
