Oligosaccharides are carbohydrates composed of a few sugar units, typically ranging from two to ten. They are an important class of biomolecules found in various biological systems, including plants, animals, and microorganisms. Oligosaccharides play crucial roles in biological processes such as cell recognition, signaling, and immune response. They can be classified based on their structure and composition, with common types including oligosaccharides derived from lactose, raffinose, and stachyose.

In plants, oligosaccharides often serve as storage forms of carbohydrates and are involved in plant defense mechanisms. For example, raffinose family oligosaccharides (RFOs) are found in legumes and are known to have anti-nutritional effects in humans. In animals, oligosaccharides are involved in various physiological functions, including the regulation of gut microbiota and the immune system. They are also found in the cell walls of certain bacteria and fungi, where they contribute to structural integrity and protection against environmental stresses.

Oligosaccharides can be synthesized through enzymatic reactions or chemical methods. They are used in various applications, including food additives, pharmaceuticals, and biomedical research. For instance, oligosaccharides derived from lactose are used as prebiotics to promote the growth of beneficial gut bacteria. In the pharmaceutical industry, oligosaccharides are used as carriers for drug delivery and as components in vaccines.

Despite their importance, the study of oligosaccharides is still in its early stages, and much remains to be understood about their biological functions and potential applications. Ongoing research aims to elucidate the molecular mechanisms underlying oligosaccharide functions and to develop new technologies for their synthesis and utilization.
