名稱:木聚糖 xylan
型號(hào):[9014-63-5]
俗稱半纖維素。木聚糖與纖維素結(jié)合,普遍存在于植物細(xì)胞壁中,在玉米芯、甘蔗渣中含量豐富,常以糖苷或游離狀態(tài)存在于樹皮、果實(shí)、木質(zhì)、葉、根、樹脂提取液中。主要是生物、醫(yī)藥和化工行業(yè)原料。
一些木聚糖常含有少量其他的糖,如 L-阿拉伯糖、D-葡萄糖、D-半乳糖、D-甘露糖、D-葡萄糖醛酸和D-半乳糖醛酸等,它們常以接枝的方式形成支鏈。木聚糖溶于稀堿中,可與纖維素分開。木聚糖與強(qiáng)酸共熱水解,是工業(yè)上制備糠醛的方法。在稀酸中水解,得木糖,是制備木糖醇的主要原料。
Commonly known as hemicellulose. Xylan exists in plant cell wall, in the corn cob, sugar cane-rich slag. Hemicellulose xylan is the major structural forms, from β-D-pyranose wood to 1 → 4 bond. Their nature and composition has not yet been determined so far.
Xylanase containing some amount of regular sugar, such as L-arabinose, D-glucose, D-galactose, D-mannose, D-glucuronic acid and D-galacturonic acid, etc., they often grafted the formation of branched-chain manner. Soluble in dilute alkaline xylanase can be separated and the cellulose. A total of xylan hydrolysis with strong acid, is prepared on industrial furfural method. In the acid hydrolysis, xylose is the main raw material for preparation of xylitol.
