# Understanding Disaccharides: Acetals and Hemiacetals### Objective:Identify whether each of the following disaccharides contains:- Two acetal carbon atoms- Two hemiacetal carbon atoms- One acetal and one hemiacetal carbon atom### Disaccharide Structures:#### Diagram (a):**Structure Description:**- The disaccharide is composed of two monosaccharide units linked through an ether (glycosidic) bond. Each monosaccharide unit includes hydroxyl groups, indicated by -OH.**Options for Diagram (a):**- One acetal and one hemiacetal carbon atom- Two hemiacetal carbon atoms- Two acetal carbon atoms#### Diagram (b):**Structure Description:**- This disaccharide also consists of two linked monosaccharide units with a glycosidic bond. The structure displays several hydroxyl groups attached to each of the cyclic components.**Options for Diagram (b):**- One acetal and one hemiacetal carbon atom- Two hemiacetal carbon atoms- Two acetal carbon atoms### Explanation:- **Acetal Carbon Atom:** A carbon atom bonded to two -OR groups, typically formed when a hemiacetal carbon reacts further with an alcohol.- **Hemiacetal Carbon Atom:** A carbon atom bonded to one -OH group and one -OR group, formed when an aldehyde reacts with an alcohol.Decide the correct classification based on the structural analysis of the disaccharide components. Indicate whether the members of each of the following pairs of monosaccharides have the same molecular formula.(a) **D-glyceraldehyde** and **2-deoxy-D-ribose**- ○ no- ○ yes
