【正文】 纖維素及其在實(shí)際生活中的應(yīng)用綜述摘要：（cellulose）是由葡萄糖組成的大分子多糖。不溶于水及一般有機(jī)溶劑。是植物細(xì)胞壁的主要成分。纖維素是自然界中分布最廣、含量最多的一種多糖，占植物界碳含量的50%以上。棉花的纖維素含量接近100%，為天然的最純纖維素來源。一般木材中，纖維素占40～50%，還有10～30%的半纖維素和20～30%的木質(zhì)素；此外，用分離純化的纖維素做原料，可以制造人造絲，賽璐玢以及硝酸酯、醋酸酯等酯類衍生物和甲基纖維素、乙基纖維素、羧甲基纖維素鈉等醚類衍生物，用于石油鉆井、食品、陶瓷釉料、日化、合成洗滌、石墨制品、鉛筆制造、電池、涂料、建筑建材、裝飾、蚊香、煙草、造紙、橡膠、農(nóng)業(yè)、膠粘劑、塑料、炸藥、電工及科研器材等方面。人類膳食中的纖維素主要含于蔬菜和粗加工的谷類中，雖然不能被消化吸收，但有促進(jìn)腸道蠕動(dòng)，利于糞便排出等功能。草食動(dòng)物則依賴其消化道中的共生微生物將纖維素分解，從而得以吸收利用。關(guān)鍵詞：纖維素 工業(yè)應(yīng)用 日常生產(chǎn) 建筑及化工 動(dòng)植物吸收Celluloseand itsapplicationin real lifereviewAbstract：Cellulose (cellulose) is posed of glucose molecules from the polysaccharide. Insoluble in water and mon organic solvents. Is the main ponent of plant cell walls. Cellulose is the most widely distributed in nature, a most abundant polysaccharide, representing 50% of the carbon content of the vegetable kingdom over. Cotton cellulose content close to 100%, for the most natural source of pure cellulose. General wood, cellulose accounted for 40 to 50%, and 10 to 30% of the hemicellulose and 20 to 30% of the lignin；Moreover, the separation and purification of cellulose as raw material, can produce rayon, cellophane, and nitrate, acetate and methyl ester derivatives such as cellulose, ethyl cellulose, sodium carboxymethyl cellulose ethers derivatives,used in oil drilling,food,ceramic glazes,chemical, synthetic detergent, graphiteproducts, pencil manufacturing, batteries, paints, building materials, decoration,incense, tobacco, paper, rubber,agriculture, adhesives, plastics, explosives, electrical and scientific equipment and so human diet mainly containscellulose in vegetables and cereals in the rough, although can not be digested and absorbed, but the promo
