Okra mucilage

Okra-mucilage R rhamnogalacturonan (with GIcA, 4-linked galacto- oligosaccharide) anti-complementary activity Abelmoschus esculentus L., roots 1989 [38]... 

Mucilage of slippery elm 96, 97) flaxseed mucilage (55, 99), okra mucilage 100) mucilage of Plantago arenaria 101) Oakwood 102)... 

Okra polysaccharides are already viscous in diluted solutions (0.5%), and the viscosity increases rapidly with increasing concentration. Heating increases their solubility, but after some time leads to irreversible loss of viscosity caused by hydrolysis. The maximum viscosity is achieved at pH 6-9. Okra mucilage is a typical polyelectrolyte. It has hypoglycaemic effects. 

The terminal disaccharide of the ceramide trihexoside isol. from normal human kidney and erythrocytes a dcgradn. prod, of mucilage from common okra (Hibiscus esculentus) formed by the action of P-galactosidase on i>galactose The simplest structural unit capable of bacterial fimbriae binding associated with initiation of bacterial infections. Cryst. (MeOH/ l-butanol/H20). 

Reducing disaccharide. Widespread as the aldobiouronic acid unit of plant polysaccharides, particularly of plant mucilages and gums. e.g. isol. from or detected in partial acid hydrolysates of Linum usitatissimum (flax), Ulmus fulya (slippery ehn), Plantago seed, Hibiscus esculentus (okra), Salvia aegytica mucilages and others. Amorph. [a]o +50.8 (H2O). [a] +96.1 (c, 0.4 in H2O). [a]g +105.5 (c, 1.06 in H2O).
