**Question 7:** *Which classification(s) is(are) applicable to maltose?* ![Maltose Diagram] The image shows the chemical structure of maltose, which consists of two glucose units connected by an α(1→4) glycosidic bond. Each glucose molecule has a CH₂OH group and hydroxyl (OH) groups attached to its carbon atoms. **Options:** - **A.** Nonreducing sugar. - **B.** Reducing sugar. - **C.** Peptidoglycan. - **D.** Glucoside. - **E.** Both B and D. **Correct Answer:** E. Both B and D. Maltose is classified as a reducing sugar and also a glucoside due to the presence of the glycosidic bond.

Below is the Fischer projection of D-galactose. Which is the proper Haworth projection of β-D-galactopyranose? The image displays the Fischer projection of D-Galactose, a simple sugar, as follows: ``` H | H—C—O—H | H—C—OH | HO—C—H | H—C—OH | HO—C—H | CH2OH ``` Labels: D-Galactose Below the Fischer projection, there are four Haworth projection options labeled I, II, III, and IV. These options depict different cyclic forms of the sugar molecule. 1. **Option I:** A six-membered ring with the structure HOCH₂ on the left side and an OH group above the top carbon atom. 2. **Option II:** A six-membered ring with the structure HOCH₂ on the left side and an OH group below the top carbon atom. 3. **Option III:** A six-membered ring with the structure CH₂OH on the right side and an OH group above the top carbon atom. 4. **Option IV:** A six-membered ring with the structure CH₂OH on the right side and an OH group below the top carbon atom. Each option is associated with a radio button labeled A, B, C, and D corresponding to options I, II, III, and IV respectively. The task is to select the proper Haworth projection for β-D-galactopyranose.
