The regulatory role of protein kinase C (PKC) in glycogen metabolism in pectin fed rats was investigated. Administration of pectin (5 g/kg body wt/day) from cucumber (Cucumis sativius L.) led to inhibitory effects on PKC activity in the liver of rats. In the brain and pancreas, PKC activity was significantly higher in pectin-treated rats as compared to the control group. Level of blood glucose ...

Cerium binding activity of three different water soluble pectin compounds of different origin was studied in a batch sorption system. The Langmuir, Freundlich and BET sorption models were adopted to describe the binding reactions between metal ions and pectin molecules. The Langmuir model provided the best fit. Within the pH range from 4.0 to 6.0, the largest amount of the cerium ions was bound...

Pectin fragments have powerful anti-metastatic properties but the molecular structure of the active component(s) is still unknown. Pectin hydrogels are used to encapsulate drugs for oral drug delivery. This polysaccharide is not digested in the upper intestinal tract but its degradation in the colon releases oligomers with potential bioactivity. Here we tested the release of pectin fragments in...

Pectin derived from plant waste sources is currently focused as an economical and eco-friendly approach. Optimization of pectin extraction from muskmelon peel by response surface methodology (RSM) was investigated in this study. Box-Behnken Design (BBD) was used to identify the optimal level of the extraction variables such as time, pH and temperature. A second-order model equation for pectin e...

pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...

Modified Citrus Pectin Introduction Modified citrus pectin (MCP), also known as fractionated pectin, is a complex polysaccharide obtained from the peel and pulp of citrus fruits. Modified citrus pectin is rich in galactoside residues, giving it an affinity for certain types of cancer cells. Metastasis is one of the most life-threatening aspects of cancer and the lack of effective anti-metastati...

Pectin is a natural polysaccharide used in food and pharma industries. Pectin degree of methylation is an important parameter having significant influence on pectin applications. A rapid, fully automated, kinetic flow method for determination of pectin methyl esters has been developed. The method is based on a lab-made analyzer using the reverse flow-injection/stopped flow principle. Methanol i...

BACKGROUND This study was conducted to evaluate the effects of consuming thermally oxidized oil supplemented with pectin on liver glutathione peroxidase activity, serum malondialdehyde and lipid profiles in male Sprague-Dawley rats. METHODS Fifty growing male Sprague-Dawley rats were randomly divided into different groups. The diets differed only in their fat and pectin content. The diets had...

Aluminum (Al) toxicity is the primary factor limiting crop growth in acidic soils. Boron (B) alleviates Al toxicity in plants, which is mainly considered to be due to the formation of Rhamnogalacturonan II-B (RGII-B) complexes, which helps to stabilize the cytoskeleton. It is unclear yet whether this is due to the increasing of net negative charges and/or further mechanisms. Kinetics of Al accu...

The main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. Pellet cores of budesonide were prepared by extrusion / spheronization technique. Pectin, in different ratios was combined with Eudragit RS30D, Eudragit NE30D or Surelease to produce film coating. The dissolution profiles of pectin coated pellets were investigated in pH of 1.2 (2 ...
