What is Xylan ?
Xylan (CAS number: 9014-63-5) is a group of hemicelluloses that are found in plant cell walls and some algae. Xylans arepolysaccharides made from units of xylose (a pentose sugar). Xylans are almost as ubiquitous as cellulose in plant cell walls and contain predominantly β-D-xylose units linked as in cellulose.
Typically the content of xylans in hardwoods are 10 - 35 % of the hemicelluloses and in softwoods they are 10 - 15 % of the hemicelluloses. The main xylan component in hardwoods is O-acetyl-4-O-methylglucuronoxylan and in softwoods the main xylan components are arabino-4-O-methylglucuronoxylans. In general softwood xylans differ from hardwood xylans by the lack ofacetyl groups and the presence of arabinose units linked by α-(1,3)-glycosidic bonds to the xylan backbone.[1]
Some macrophytic green algae contain xylan (specifically homoxylan[2]) especially those within the Codium and Bryopsisgenera[3] where it replaces cellulose in the cell wall matrix. Similarly, it replaces the inner fibrillar cell-wall layer of cellulose in some red algae.
Xylan is one of the foremost anti-nutritional factors in common use feedstuff raw materials.
Xylooligosaccharides produced from xylan are considered as "functional food" or dietary fibers [4] due their potential prebiotic properties [5]. Xylan can be converted in xylooligosaccharides by chemical hydrolysis using acids [6] or by enzymatic hydrolysis using endo-xylanases [7]. Some enzymes from yeast can exclusively converts xylan into only xylooligosaccharides-DP-3 to 7.[8]

Application
Partial degradation of xylan can form xylooligosaccharides. Low xylan has wide application value, low sweetness, low calorie, difficult to be digested and absorbed by the human body, but can be fermented, basically does not increase blood sugar and blood lipids, and has a laxative Features. It has significant Bifidobacterium value-adding ability, and intestinal bacteria have poor utilization rate. It has no caries, can promote the absorption of calcium and iron in the human body, enhances human immunity, and is suitable for functional health foods. It is the main functional oligosaccharide.
