Interactions of Condensed Tannins with Selected Proteins
The relative affinities ufeondensed tannins purilied from sorghum, pinto bean, quebracho and wattle for six dissimilar protins have been determined by a competitive binding assay. The results indicate that tannin/protein interactions may be specific for different tanains as well as for different proteins. The highly specific interactions suggest that the differences in affinity are functionally...
متن کاملCucumber fruit quality at harvest affected by soilless system, crop age and preharvest climatic conditions during two consecutive seasons
Cucumber fruits (Cucumis sativus L., cv. Trópico F1) grown on perlite substrate and NFT (Nutrient Film Technique) were harvested during two seasons (winter and spring) to monitor the effects of climatic conditions and hydroponic growth systems on fruit quality at harvest. The best fruit quality at harvest, as measured by lightness and hue angle parameters, was obtained during the 3 weeks follow...
متن کاملThe implications of condensed tannins on the nutritive value of temperate forages fed to ruminants.
New methodology for measuring forage condensed tannin (CT) content is described and the effects of CT upon forage feeding and nutritive value for ruminant animals are reviewed. CT react with forage proteins in a pH-reversible manner, with reactivity determined by the concentration, structure and molecular mass of the CT. Increasing concentrations of CT in Lotus corniculatus and Lotus pedunculat...
متن کاملThe digestibility in piglets of faba bean (Vicia faba L.) as affected by breeding towards the absence of condensed tannins.
Seed samples from two near-isogenic faba bean (Vicia faba L.) lines were examined for the levels of so-called anti-nutritional factors (ANF). From the ANF known to be present in faba beans, trypsin inhibitor activity, functional lectins, condensed tannins and pyrimidine glycosides were analysed. It was concluded that the lines differed only in the content of condensed tannins being < 0.5 g/kg a...
متن کاملRuminal biohydrogenation as affected by tannins in vitro.
The aim of the present work was to study the effects of tannins from carob (CT; Ceratonia siliqua), acacia leaves (AT; Acacia cyanophylla) and quebracho (QT; Schinopsis lorentzii) on ruminal biohydrogenation in vitro. The tannins extracted from CT, AT and QT were incubated for 12 h in glass syringes in cow buffered ruminal fluid (BRF) with hay or hay plus concentrate as a substrate. Within each...
