Final answer:
A glycosidic bond is the bond formed between two sugar molecules in a dehydration synthesis reaction, such as the one that creates sucrose from glucose and fructose.
Step-by-step explanation:
The bond between two sugar molecules formed via a dehydration process is called a glycosidic bond. This type of bond is created when two monosaccharides, such as glucose and fructose, combine in a dehydration reaction, wherein a water molecule is lost. For instance, sucrose is formed through a glycosidic linkage between specific carbon atoms of the two monosaccharides involved. The formation of a glycosidic bond is an example of dehydration synthesis, where the hydroxyl (OH) group from one sugar molecule and a hydrogen (H) from another sugar molecule are removed, producing water.
It's important to note that the different bonds mentioned have specific roles in biology. A peptide bond is the bond formed between two amino acids. A phosphodiester bond is formed between adjacent nucleotides in nucleic acids. The glycosidic bond, on the other hand, is unique to carbohydrates, making it the correct answer to the question about sugar molecules.
