Example sentences for: polysaccharides
How can you use “polysaccharides” in a sentence? Here are some example sentences to help you improve your vocabulary:
It has been proposed that the GAG-binding property of PEDF provides the molecular basis for its association with extracellular matrices and may serve to localize PEDF activity in the retina and CNS [ 14 19 ] . However, the present results point to direct effects these polysaccharides might have on the biochemical interactions between PEDF and PEDF receptors on the surfaces of cells that respond to this neurotrophic factor.
Scorpion venom when injected exerts a strong inflammatory response [ 11 ] . Many plant species used against stings contain compounds with antiinflammatory properties, flavonoids (rutin, hesperidin, quercetin), coumarins (bergapten), coumestans (wedelolactone), triterpenes, sterols and saponins [ 38 11 ] . The mechanism of action of the flavonoids is based on the inhibition of enzymatic steps in the arachidonic acid cascade [ 38 ] . Plant compounds that are immunostimulants at very low doses are some alkaloids, quinones, isobutylamides, phenolcarboxylic acid esters and terpenoids [ 39 ] . Other plant compounds with immunostimulatory effects are sesquiterpene lactones [ 40 ] . Many polysaccharides and glycoproteins enhance the unspecific immune system by activating the phagocytotic activity of granulocytes and macrophages, or by inducing cytokine production or influencing complement factors [ 39 ] .
The protective effects of antibody to pneumococcal capsular polysaccharides have been appreciated since the development of serum therapy, in which passively transferred, serotype-specific antipneumococcal serum reduced mortality from pneumococcal pneumonia by half [1].
These polymers belong to several classes: (1) sulfate esters of polysaccharides (dextrin and dextran sulfates [ 1 2 3 4 5 6 7 8 9 10 11 ] ; cellulose sulfate [ 12 13 14 15 ] ; sulfate esters of galactose + 3,6-anhydrogalactose copolymers {carrageenan; [ 1 16 17 18 19 ] }); (2) polymers containing sulfonated benzene or naphthalene rings {poly(styrene-4-sulfonate) [ 20 21 ] } and naphthalene sulfonate polymers {PRO2000 [ 22 23 24 ] }; and (3) polycarboxylates (acrylic acid polymers {Carbomer 974P; BufferGel [ 25 26 27 28 29 ] }); and acetyl phthaloyl cellulose {cellulose acetate phthalate (CAP) [ 30 31 32 33 34 35 36 37 ] }.
Interestingly, CAP-gp120 binding also occurs in 1M NaCl, conditions under which binding of sulfated polysaccharides to gp120 is abolished [ 43 ] . This suggests that electrostatic interactions do not play an exclusive role in CAP-gp120 binding [ 51 ] .
