Solution
The correct option is AC1−C4 glycosidic linkage Cellulose occur in the cell wall of plants and in certain animal tissues. Itts main source is cotton and wood. It is a non-reducing carbohydrate. It has a very high molecular weight. Cellulose is formed only by the β− D-glucose units. These glucose units are linked by C1−C4 glycosidic linkage to form the cellulose structure. −OH group of C1 carbon of one glucose and −OH of C4 carbon of another gluocse unit combine to form C1−C4 glycosidic linkage.
