Given below are four statements regarding the structure of carbohydrates: (A) The glycosidic linkage in maltose is between C1 of -D-glucose and C4 of another -D-glucose. (B) Sucrose is a non-reducing sugar because the glycosidic linkage involves C1 of -D-glucose and C2 of -D-fructose. (C) Amylose is a branched polymer of -D-glucose containing both -1,4 and -1,6 glycosidic linkages. (D) Lactose contains a -1,4 glycosi

Step-by-step solution

Statement (A) is correct. Maltose is composed of two -D-glucose units linked at C1 and C4. Statement (B) is correct. Sucrose is non-reducing because both reducing groups (C1 of glucose and C2 of fructose) are involved in glycosidic bond formation. Statement (C) is incorrect. Amylose is a linear, unbranched polymer of -D-glucose held together by only -1,4 glycosidic linkages. Amylopectin is the branched component containing both -1,4 and -1,6 linkages. Statement (D) is incorrect. The glycosidic linkage in lactose is
