Heteropolysaccharides are complex carbohydrates composed of more than one type of monosaccharide unit. Unlike homopolysaccharides, which consist of repeating units of a single monosaccharide, heteropolysaccharides have a varied structure. The different monosaccharide components can be arranged in a linear or branched fashion, and their linkage can vary, leading to a wide range of structural possibilities and properties. These complex structures often result in unique biological functions.

Heteropolysaccharides play crucial roles in many biological systems. In bacteria, they are often found as components of the cell wall or capsule, contributing to the organism's structural integrity and ability to evade host immune responses. For example, the capsule of many bacteria is a heteropolysaccharide that provides protection and aids in adhesion. In higher organisms, heteropolysaccharides are integral parts of connective tissues, where they provide structural support and lubrication. Examples include glycosaminoglycans like hyaluronic acid and chondroitin sulfate, which are important for joint function and tissue hydration. They can also be involved in cell-cell recognition and signaling processes. The diversity in their composition and structure allows heteropolysaccharides to perform a multitude of specialized functions in both prokaryotic and eukaryotic organisms.
