Solution properties of polygalacturonic acid.
1. The specimen of polygalacturonic acid used in these studies was shown to contain very little neutral sugar, methyl ester groups or ash, and only residues of galacturonic acid. Its electrophoretic homogeneity was examined in pyridine-acetic acid buffer at pH6.5 and in borate buffer at pH9.2. The distribution of effective particle weights was shown to be fairly narrow. 2. The pH-titration curv...

15 صفحه اولThe effect of poly-L-lysine structure on the pH response of polygalacturonic acid-based multilayers.
The effect of poly-L-lysine (PLL) molecular weight and structure on pH stability of polygalacturonic acid (PGaLA)-based multilayer films is studied over a pH cycle 7.0-1.6-7.0. The multilayer assembled with the lowest molecular weight PLL (1 kDa) showed the largest pH response. Only 12% of the mass remained and a preferential loss of PLL was observed. Extensive structural reorganisation of the ...
متن کاملEffect of treated polygalacturonic acid on blood volume loss in the rat following traumatic injury.
Evidence is presented that a polygalacturonic acid derivative (Stypturon) when administered intravenously to rats in nn optimal dosage results in concomitant diminution of blood loss from experimental injury to the tail. Mortality rate associated with hemorrhagic shock was significantly reduced. Blood coagulation was inhibited at the site of injury by immersion of the traumatized tail in an ant...
متن کاملDisease Association and Arthritogenic Potential of Circulating Antibodies against the a1,4-Polygalacturonic Acid Moiety
Much progress has been made in recent years on the diagnostic value, Ag specificity, and pathogenic roles of autoantibodies correlated to the development of rheumatoid arthritis (RA) in humans. However, carbohydrate Ag-specific autoantibodies that may also play important roles in RA have largely been ignored. In this article, we report that serum levels of Abs capable of recognizing a1,4-polyga...
