Polysaccharides in a sentence

Bacteria synthesize vitamins in our gut, convert the things we eat into useful sugars and polysaccharides, and go to war on alien microbes that slip down our gullet.

Algal cell walls contain either polysaccharides (such as cellulose (a glucan )) or a variety of glycoproteins ( Volvocales ) or both.

Although many polysaccharides are linear, many have branches.

As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three through ten monosaccharide units; but the precise cutoff varies somewhat according to convention.

Autotrophs such as plants can construct the complex organic molecules in cells such as polysaccharides and proteins from simple molecules like carbon dioxide and water.

Bacterial capsular polysaccharides Pathogenic bacteria commonly produce a thick, mucous-like, layer of polysaccharide.

Bacterial fermentation of undigested polysaccharides produces these.

By contrast, Laccaria bicolor possesses expanded multigene families associated with hydrolysis of bacterial and microfauna polysaccharides and proteins.

Function Structure Nutrition polysaccharides are common sources of energy.

However, the report put "fruit, vegetables and whole-grains" in the complex carbohydrate column, despite the fact that these may contain sugars as well as polysaccharides.

In addition to the polysaccharides, these matrices may also contain material from the surrounding environment, including but not limited to minerals, soil particles, and blood components, such as erythrocytes and fibrin.

In fact, the EPS matrix consists not only of polysaccharides but also of proteins (which may be the major component in environmental and waste water biofilms) and nucleic acids.

Lipids and nucleic acids are antigenic only when combined with proteins and polysaccharides.

Lipopolysaccharide is one of the most important cell-surface polysaccharides, as it plays a key structural role in outer membrane integrity, as well as being an important mediator of host-pathogen interactions.

Methods for the structure determination of oligosaccharides and polysaccharides include NMR spectroscopy and methylation analysis.

Monosaccharides, disaccharides, and polysaccharides contain one, two, and three or more sugar units, respectively.

Most of these polysaccharides exhibit useful visco-elastic properties when dissolved in water at very low levels.

Other biological polymers such as polysaccharides can also be considered to have a primary structure, although the usage is not standard.

Pectins Pectins are a family of complex polysaccharides that contain 1,4-linked α-D-galactosyluronic acid residues.

Polysaccharides are also common sources of energy.
