“By cellulose is understood a carbohydrate of the general formula C6H10O5 not soluble in water, alcohol, ether, or dilute acids but soluble in an ammoniacal solution of copper oxide. It gives with iodine and sulphuric acid a blue color and with iodine zinc chloride a violet and yields dextrose on hydrolysis.”—H. Fischer. ↩
