The correct Answer is:
To determine which is an unbranched glucan, let's analyze the options provided: 1. **Understanding Glucans**: - Glucans are polysaccharides made up of glucose units. They can be branched or unbranched depending on the type of glycosidic linkages present. 2. **Analyzing Each Option**: - **Option A: Cellulose**: - Cellulose is a fibrous homopolysaccharide composed of glucose units linked by β-1,4-glycosidic bonds. It forms a linear chain structure, which means it is unbranched. - **Option B: Starch**: - Starch is a storage polysaccharide found in plants. It consists of two components: amylose (which is unbranched) and amylopectin (which is branched). Therefore, starch as a whole is considered branched due to the presence of amylopectin. - **Option C: Glycogen**: - Glycogen is the storage form of glucose in animals. It is highly branched, with α-1,4-glycosidic bonds in the linear chains and α-1,6-glycosidic bonds at the branching points. - **Option D: All of the above**: - This option cannot be correct since both starch and glycogen are branched. 3. **Conclusion**: - The only unbranched glucan among the options is **cellulose**. Thus, the final answer is **Option A: Cellulose**.
