Tannins (hydrolysable and condensed tannin) are polyphenolic polymers of relatively high
molecular weight with the capacity to form complexes mainly with proteins due to the …

Comparative aspects of plant tannins on digestive physiology, nutrition and microbial
community in sheep and goats are discussed in the context of differences due to feed intake …

Polyphenolics are widely distributed in the plant kingdom and are often present in the diet of
herbivores. The two major groups of plant polyphenolic compounds other than lignin are …

Tannins are polyphenols characterized by different molecular weights that plants are able to
synthetize during their secondary metabolism. Macromolecules (proteins, structural …

Tannins are a prominent class of compounds which constitute the plant secondary
