Final Answer:
The given disaccharide is sucrose, which is composed of glucose and fructose linked by a glycosidic bond.
Step-by-step explanation:
Sucrose, a common disaccharide, is formed by the condensation reaction between a glucose molecule (C₆H₁₂O₆) and a fructose molecule (C₆H₁₂O₆). The glycosidic bond formed in this process is a linkage between the anomeric carbon of glucose and the hydroxyl group on the fructose molecule. In more specific terms, the glycosidic bond is formed between the C₁ carbon of glucose and the C₂ carbon of fructose, resulting in the release of a water molecule (H₂O). This linkage is commonly known as an α,β-1,2-glycosidic bond.
Analyzing the molecular structures, we observe that the glucose molecule undergoes an intramolecular reaction, resulting in the formation of a hemiacetal at the C₁ carbon. Simultaneously, the fructose molecule forms a hemiketal at the C₂ carbon. When these reactive forms combine, the glycosidic bond forms, creating a stable structure with a linkage between the C₁ carbon of glucose and the C₂ carbon of fructose. The overall chemical equation for the synthesis of sucrose can be represented as:
C₆H₁₂O₆ (glucose) + C₆H₁₂O₆ (fructose) → C₁₂H₂₂O₁₁ (sucrose) + H₂O
This reaction not only highlights the composition of sucrose but also illustrates the specific carbon-carbon linkage between the two monosaccharides. Sucrose serves as an essential source of energy in many organisms and plays a crucial role in the transport of carbohydrates in plants.
