A glucan molecule is a polysaccharide of D-glucose monomers,^[1] linked by glycosidic bonds.

Many beta-glucans are medically important. They represent a drug target for antifungal medications of the echinocandin class.

Types

The following are glucans: (The α- and β- and numbers clarify the type of O-glycosidic bond.)

Alpha

dextran, α-1,6-glucan with α-1,3-branches
glycogen, α-1,4- and α-1,6-glucan
pullulan, α-1,4- and α-1,6-glucan
starch, α-1,4- and α-1,6-glucan

Beta

cellulose, β-1,4-glucan
chrysolaminarin, β-1,3-glucan
curdlan, β-1,3-glucan
laminarin, β-1,3- and β-1,6-glucan
lentinan, a strictly purified β-1,6:β-1,3-glucan from Lentinus edodes
lichenin, β-1,3- and β-1,4-glucan
pleuran, β-1,3- and β-1,6-glucan isolated from Pleurotus ostreatus
zymosan, β-1,3-glucan

Properties

Properties of Glucans include resistance to oral acids/enzyme and water insolubility.Glucans extracted from grains tend to be both soluble and insoluble.

Biomineralization and superhydrophobicity of BaCO3 complex nanostructures.

Wu S1, Cao H, Yin S, Zhang X, Chernow V.
Inorganic chemistry.Inorg Chem.2009 Nov 2;48(21):10326-9. doi: 10.1021/ic9014724.
In this paper, we report on biomineralization of BaCO(3) hierarchical architectures with self-cleaning ability. The phase structures of the obtained samples were characterized by X-ray diffraction (XRD). All of these complex nanostructures, including dendrite-like nanostructures, dumbbell-like nanos

Journal of environmental sciences (China).J Environ Sci (China).2008;20(5):579-84.
The adsorption and desorption characteristics of Al3+ to/from humic acids at different pH, ionic strength, and temperature were studied by the C-25 glucosan-gel chromatography method. The results showed that the maximum adsorption amount (Q(max)) and adsorption constant (k) increased, whereas, the a
