Fibrolytic

Xylanase

A β-1,4-xylanohydrolase that specifically cleaves xylan, a major component of hemicellulose, into xylooligosaccharides and xylose. This activity aids in the digestion of cereal grains and woody plant materials, supporting improved fiber breakdown in plant-heavy diets.*

BIOCHEMICAL ROLE IN DIGESTION

Xylanase specifically hydrolyzes β-1,4 bonds in xylan, a major component of hemicellulose in cereal grains and plant materials. By converting complex xylans into xylose and xylo-oligosaccharides, it reduces the structural rigidity of plant cell walls and lowers intestinal viscosity. This activity supports both direct energy release from xylose and the generation of oligosaccharides that can influence colonic microbial metabolism, thus extending its role beyond the small intestine.*

NUTRITIONAL RELEVANCE IN SUPPLEMENTATION

Supplemental xylanase is particularly beneficial for individuals consuming grain-heavy diets, as it enhances the digestion of wheat, rye, and other cereals. By reducing the presence of undigested xylans in the colon, it minimizes bloating, gas, and discomfort. At the same time, its breakdown products can promote beneficial microbiota, improving gut ecology. This dual effect makes xylanase supplementation valuable both for immediate digestive comfort and for supporting long-term gastrointestinal health.*
