Mannans are a type of polysaccharide commonly found in the cell walls of plants, fungi, and some bacteria. They are composed of long chains of mannose sugar molecules linked together, and play important structural and functional roles in these organisms. Research in the area of mannans includes studies on their biosynthesis, biological functions, and potential applications in various industries such as food, pharmaceuticals, and biofuels. Understanding the structure and properties of mannans can provide valuable insights into their potential uses and benefits in different fields.
