Verified step by step guidance1
Understand the concept of dehydration synthesis: This is a chemical reaction where two molecules are joined together with the removal of a water molecule. In the context of carbohydrates, this typically involves the formation of glycosidic bonds.
Identify the reactants: In carbohydrate dehydration synthesis, the reactants are typically monosaccharides, which are simple sugars like glucose or fructose.
Recognize the process: During dehydration synthesis, a hydroxyl group (OH) from one monosaccharide and a hydrogen atom (H) from another monosaccharide are removed, forming a water molecule (H₂O).
Form the product: The removal of water allows the remaining oxygen atom to form a covalent bond between the two monosaccharides, resulting in a disaccharide or polysaccharide.
Summarize the outcome: The primary result of dehydration synthesis in carbohydrates is the formation of larger carbohydrate molecules, such as disaccharides or polysaccharides, through the removal of water.
