LEVAN Meaning and Definition

  1. Levan is a term that can be categorized within two different contexts: biology and chemistry.

    In the field of biology, levan refers to a type of polymer composed of fructose units that are connected by beta-2,6 glycosidic bonds. It is categorized as a fructan, which is a group of naturally occurring carbohydrates. Levan is commonly found in bacteria, particularly in species belonging to the genus Bacillus and Zymomonas mobilis. These microorganisms produce levan as a storage carbohydrate to provide them with energy during periods of nutrient deprivation.

    In the realm of chemistry, levan is described as a type of polysaccharide that contains fructose monomers linked together through beta-2,6 glycosidic bonds. It is structurally similar to inulin, another fructan polymer. Levan can be derived from various sources, such as plants (e.g., dahlia tubers) or synthesized artificially through enzymatic or chemical methods. It has applications in the food industry as a thickening or stabilizing agent due to its high molecular weight and ability to form gels. Additionally, levan is utilized in the production of functional foods and as a prebiotic, providing health benefits by promoting the growth of beneficial intestinal bacteria.

    In summary, levan is a type of fructan polymer present in microorganisms or obtained from plant sources. It serves as an energy storage carbohydrate in bacteria and finds applications as a thickening agent in the food industry as well as in the production of functional foods and prebiotics.
