Specificity of Tannin Binding Salivary Proteins Relative to Diet Selection by Mammals

摘要: The tannin-binding specificity of salivary proteins in several mammals was investigated as a possible explanation for observed food habits. Moose (Alces alces) and beaver (Castor canadensis) produce that only bind the linear condensed tannins common their preferred foods, such willow, aspen, or birch. mule deer (Odocoileus hemionus), which has more generalized diet, produces branched-chain gallotannins, but not an ellagitannin. omnivorous black bear (Ursus americanus) all types tannins. In feeding trials were fed bound by vitro assays. results confirmed these reduce digestibility than are proteins. Thus, always scavengers dietary tannins, can be very specific t...
