Exempel på pectin

• In summary, our results show for the first time an important role for a soluble fibre, pectin, in modifying parasite biology.

• Following in vitro culture of female worms, increasing levels of dietary pectin were associated with increasing release of eggs.

• This inactivation step significantly reduced the release of water-soluble and oxalate-soluble pectins (data not shown).

• Species variability in boron requirement is correlated with cell wall pectin.

• All regression lines were statistically significant for pectin but none were statistically significant for cellulose (see text for details).

• However, an analysis of pectin and pectin methyl esters in developing and maturing soybean seeds has not been reported.

• In vitro egg production increased linearly whereas in vivo per capita egg production increased then declined with increasing concentrations of pectin.

• Two classes of fibre exist : cellulose and lignins comprise the insoluble fraction while pectin, guar gum and hemicellulose form the soluble fraction.

• Water-soluble fibre (pectin) or water-insoluble fibre (cellulose) was added to the diet separately at 5, 10 and 20 % levels.

• We suggest that pectin promoted parasite establishment through effects on bile sequestration in the lumen.

• Site specific changes in pectin esterification may facilitate cell wall folding during desiccation.

• Yet this pattern was not observed in vivo, where per capita egg production peaked at the 10 % pectin concentration, but was very low in mice fed 20 % pectin.

• Thus, increasing concentrations of pectin and cellulose could also be advantageous to the survival and reproduction of the parasite if intestinal morphology responds similarly in infected mice.

• Effects of differing purified cellulose, pectin and hemicellulose fiber diets on mucosal morphology in the rat small and large intestine.

• Parasite establishment was elevated in mice fed 20 % pectin, but was unaffected by cellulose concentration.
