α-cellulose - Alpha cellulose (English spelling) α-cellulose

Japanese: α‐セルロース - アルファセルロース(英語表記)α‐cellulose
α-cellulose - Alpha cellulose (English spelling) α-cellulose
The name of cellulose obtained by soaking cellulose fibers (mainly chemical pulp) in a 17.5% aqueous solution of sodium hydroxide and washing the insoluble parts with water. Cellulose is a polysaccharide that makes up the cell membranes of higher plants and is a polymer of glucose (dextrose). Cotton cellulose contains only small amounts of impurities, so they can be easily removed. Wood cellulose is tightly bound to hemicellulose and lignin, which are polymers of sugars other than glucose, and a process similar to that used in chemical pulp manufacturing is required to remove them.

Japanese:
セルロースからなる繊維(主としてケミカルパルプ)を17.5%の水酸化ナトリウム水溶液に浸し,不溶解部分を水で洗って得られるセルロースの名称。セルロースは高等植物の細胞膜を構成する多糖類で,グルコース(ブドウ糖)の重合体である。綿セルロースは不純物を少ししか含まないので簡単に取り除くことができる。木材セルロースは,グルコース以外の糖の重合体であるヘミセルロースやリグニンとかたく結びついており,それらを取り除くにはケミカルパルプの製造法のような処理が必要である。
