Mannans are a type of complex carbohydrate or polysaccharide that is primarily composed of the sugar mannose. They are commonly found in various natural sources such as plants, fungi, and bacteria. Mannans are characterized by their linear or branched structures, consisting of repeating mannose units connected by glycosidic linkages.
Mannans have diverse biological functions and are involved in various biological processes. In plants, they can be present in the cell wall and play a role in structural support, cell adhesion, and protection against pathogens. Mannans can also function as reserve carbohydrates, providing energy storage. In some bacteria, mannans are components of the slime layer, which helps in biofilm formation and adhesion to surfaces.
Due to their unique properties, mannans find applications in several industries. They are used as thickeners, stabilizers, and emulsifiers in the food and beverage industry. Mannans also have potential applications in medicine, particularly in the development of drug delivery systems and as immunomodulators. Additionally, they have been studied for their prebiotic properties, promoting the growth of beneficial gut bacteria.
In summary, mannans are complex carbohydrates composed primarily of mannose units. They have diverse functions and can be found in various natural sources. With their possible applications in industries and medicine, mannans offer a wide range of opportunities for research and development.
