Heteropolysaccharides, also known as heteroglycans, are complex carbohydrates composed of more than one type of monosaccharide unit. This distinguishes them from homopolysaccharides, which are made up of repeating units of a single monosaccharide. The specific arrangement and types of monosaccharides, as well as the linkages between them, determine the unique properties and functions of each heteropolysaccharide.

These complex structures are widespread in nature and play diverse roles. In plants, they are essential components of cell walls, providing structural support and integrity. Examples include pectins and hemicelluloses, which contribute to the rigidity and flexibility of plant tissues. In animals, heteropolysaccharides are found in connective tissues, such as cartilage and skin, where they contribute to lubrication and hydration. Glycosaminoglycans (GAGs) are a major class of animal heteropolysaccharides, often sulfated and highly charged, which are crucial for tissue structure and biological processes.

Bacterial heteropolysaccharides are also significant, often forming capsules or slime layers around bacterial cells. These structures can protect bacteria from environmental stresses, aid in adhesion to surfaces, and contribute to virulence by evading host immune responses. The study of heteropolysaccharides is important for understanding biological structures, developing new biomaterials, and exploring therapeutic applications. Their complexity offers a vast array of potential applications in fields ranging from medicine to food science.
