<p><b>New page</b></p><div>'''Levan polysaccharide''' is a type of [[polysaccharide]] that is composed of [[fructose]] residues. It is produced by certain [[bacteria]] as a form of energy storage and is also found in some plants. The term "levan" comes from the Latin word "levare", which means "to raise", referring to the ability of this polysaccharide to increase the viscosity of solutions.<br />
<br />
==Etymology==<br />
The term "levan" is derived from the Latin word "levare", which means "to raise". This refers to the ability of levan polysaccharide to increase the viscosity of solutions. The term was first used in this context in the mid-20th century.<br />
<br />
==Structure and Properties==<br />
Levan polysaccharide is a type of [[beta-2,6-fructan]], meaning it is composed of fructose residues linked by beta-2,6 glycosidic bonds. It is a high molecular weight polysaccharide, typically ranging from 10,000 to 1,000,000 Daltons. Levan polysaccharide is soluble in water and forms a viscous solution.<br />
<br />
==Production and Uses==<br />
Levan polysaccharide is produced by certain bacteria, including [[Bacillus subtilis]] and [[Zymomonas mobilis]], as a form of energy storage. It is also found in some plants, including barley and wheat. Levan polysaccharide has a number of potential uses, including as a food additive, in pharmaceuticals, and in the production of biofuels.<br />

==Related Terms==<br />
* [[Polysaccharide]]: A type of carbohydrate that consists of a number of sugar molecules bonded together.<br />
* [[Fructose]]: A simple sugar that is found in many plants and is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion.<br />
* [[Bacteria]]: A type of biological cell. They constitute a large domain of prokaryotic microorganisms.<br />
