title: Mineral absorption by albino rats as affected by some types of dietary pectins with different degrees of esterification.
abstract: Male albino rats were fed diets contained 6.85% mineral salts for 2 weeks (adaptation condition). Then they were fed the dietary pectin administered diet for 6 weeks to evaluate the effect of administration of pectin on the absorption of some monovalent, bivalent and heavy metals in the serum of rats. The experimental parameters included, monovalent minerals (K, Na), bivalent minerals (Zn, Cu, Ca, Fe), heavy metals (Pb, Cd), serum uric acid and serum creatinine. The obtained results indicated that the serum contents of monovalent minerals were negatively affected by pectin administration. The low degree of esterification of pectin was more effective on the absorption of bivalent minerals. Also, the rat serum levels of lead and cadmium were reduced by pectin administration. Serum total proteins were reduced by pectin administration. The level of rat serum of uric acid and creatinine fed different sources of pectin were within normal levels and were insignificantly lower than that recorded for control samples.
