| 体外研究 | Xylan is a major plant polysaccharide present in secondary walls of tracheary elements and fibers as well as in primary walls of parenchyma cells in grasses. It is composed of a linear chain ofβ-1,4-linked xylosyl residues that are often decorated with 2- O -linked glucuronic acid (GlcA)/methylated glucuronic acid (MeGlcA). |

xylan from beechwood - 介绍
木聚糖（xylan）为多聚五碳糖，是半纤维素的一种，广泛存在于植物细胞壁中，是自然界含量仅次于纤维素的碳水化合物。由木糖红β-1，4-糖苷键连接而成，分子量约30000（200个糖单位），白色无定形粉末，溶于稀碱溶液，随样品不同，旋光度[α]D-71·2°到-109·5°。存在于陆上、海中的植物的茎中及谷皮中。先用稀碱从上述材料中抽提，然后加酸至PH值4·2使其沉淀，重复此过程，可制得较纯的木聚糖。

xylan from beechwood - 简介
木聚糖是一种多糖类化合物，由葡萄糖分子组成。它是一种无色、无味、不溶于水的固体。
制备木聚糖的方法主要有两种：酸水解法和酶法。酸水解法是通过将木材原料与酸进行反应，将木素分解为木聚糖。而酶法是利用特定的酶对纤维素进行降解，生成木聚糖。
安全性，木聚糖是一种天然产物，通常被认为是无毒的。它对人体和环境没有明显的危害。如同使用任何化学物质一样，应注意正确使用和储存，以避免意外接触。在工业生产和应用中应遵守相应的安全操作规程。
