What is dehydration synthesis?

Dehydration synthesis refers to a specific type of chemical reaction in which two molecules are covalently bonded together through the removal of a water molecule. This process is essential in the formation of larger biological macromolecules such as carbohydrates, proteins, and nucleic acids. During dehydration synthesis, a hydroxyl group (-OH) is removed from one molecule and a hydrogen atom (H) is removed from another, resulting in the formation of water (H2O) and the new covalent bond between the two original molecules. This reaction is vital for building complex molecules from simpler ones, playing a crucial role in various biological processes. Understanding dehydration synthesis is essential for grasping how polymers are formed, which is fundamental to many aspects of biology, including metabolism and the structure of cells.
