Milligram quantities of oligogalacturonic acids up to a degree of polymerization (DP) of 20 were purified by high-performance anion-exchange chromatography utilizing a preparative-scale (21-mm i.d.) CarboPac PA1 column and a nonlinear potassium aceta

Direct isothermal titration calorimetric measurement of Δ H and Δ S for the inclusion of chlorogenic acid (CA) by epichlorohydrin-polymerized cyclomaltoheptaose (β-cyclodextrin, β-CD n ), β-CD, and hydroxypropyl-β-CD (HP-β-CD) was performed at

Cyclomaltooligosaccharides (cyclodextrins, CDs) increase cutinase activity with both naturally occurring and synthetic cuticular substrates. Little is known about the interactions of CDs with cutin or cutin-like substrates such as 16-hydroxypalmitate

A cyclomaltoheptaose (β-cyclodextrin) bonded-phase HPLC column was used for the first time to separate acidic oligosaccharides. Oligogalacturonic acids up to a degree of polymerization (dp) of 7 were separated with a 50:50 acetonitrile-sodium phosph

The inclusion complexes of cyclomaltoheptaose (β-CD) and β-CD's 50% hydroxyethyl-substituted derivative (HE-β-CD) with chlorogenic acid (CA) were studied with regard to temperature and water activity (aH2O ≈ mole fraction = XH2O = 0.8–0.99; 0.

Traditionally, UV absorption detection ( A 235 ) of 4,5-unsaturated bonds has been used to evaluate the depolymerization of pectic polysaccharides by pectate lyase (PL). This approach ignores the generation of oligogalacturonic acids without a 4,5-un

Malto-oligosaccharides up to a degree of polymerization of 8 were isolated in gram quantities by preparative HPLC from mild acid hydrolysates of cyclomaltoheptaose and cyclomatooctaose [β-cyclodextrin (βCD) and γ-cyclodextrin (γCD), respectively]

The 13C CPMAS n.m.r. spectrum of 4-O-beta-D-galactopyranosyl-D-fructose (lactulose) trihydrate, C12H22O11.3 H2O, identifies the isomer in the crystals as the beta-furanose. This is confirmed by a crystal structure analysis, using CuK alpha X-ray data

Oligogalacturonic acids up to a degree of polymerization of 7 (d.p. 7) were isolated in gram quantities by preparative h.p.l.c. from endo-polygalacturonase- and pectate lyase-depolymerized polygalacturonic acid. A Dynamax-60A NH 2 (21.4 × 250 mm) 1-
