What is the function of oligosaccrides?

Oligosaccharides serve various functions in biological systems, primarily as carbohydrate molecules composed of a small number of sugar units. They play a crucial role in cell recognition and signaling, influencing processes such as immune response and cell adhesion. Additionally, oligosaccharides can serve as prebiotics, promoting the growth of beneficial gut bacteria, and are involved in energy storage and structural functions in plants and microbes.
