In biology and chemistry, synthesis is the process of creating an organic compound especially through the aid of enzymes. DEHYDRATION & HYDROLYSIS REACTIONS. Dehydration reactions involve monomer molecules (like amino acids or simple sugars) bonding to each other.
In order to break the bonds, water must be added to the equation. To further understand this, detailed information regarding the difference between hydrolysis and dehydration synthesis is discussed below. Hydrolysis Hydrolysis means separating with the use of water. In Chemistry, Hydrolysis is a chemical reaction with water, in which a macromolecule is separated into smaller molecules.

On the other hand, in Biology, this process involves water to split polymers into monomers. The bottom line is Hydrolysis occurs when water is added to the equation to break it down or separate it.
In our bodies, Hydrolysis is the main process to release energy. When we eat food, it is digested or broken down into substances so the body can absorb it and convert it to energy.
Dehydration/ Hydrolysis Reactions
Foods, having complex molecules are broken down into simple molecules. When energy is needed for biosynthesis, ATP is hydrolyzed and stored energy is released for utilization.
Dehydration Synthesis Dehydration means to take away water, and synthesis means to build or create something. Hence, Dehydration Synthesis is defined as taking away water to build something. This process happens by removing one molecule of —OH hydroxyl group and one molecule of -H to form H2O or water.
Therefore, the final products of dehydration synthesis reactions are always complex compounds than that of the reactants. Dehydration synthesis reaction is a type of synthesis reaction since a large molecule is produced.
These dehydration synthesis reactions can also be named as condensation reactions since condensation refers to the formation of water molecules. Therefore, dehydration synthesis occurs between molecules having a hydroxyl —OH group and a proton that are available to be released. In chemical synthesis processes, dehydration synthesis is used to obtain larger molecules through releasing water molecules.
Difference Between Dehydration Synthesis and Hydrolysis | Definition, Mechanism, Examples
For example, the reaction between an alcohol and a carboxylic acid may produce an esterreleasing a water molecule as the byproduct.
Here, the —OH group of the carboxylic acid is released and the —H atom bonded to the oxygen of alcohol is also released.
Therefore, these two —OH group and —H group combine to form a water molecule. Esterification In biological systems, the terms glycosidic bonds and peptide bonds are often used to describe the bonding between molecules. Glycosidic bonds are formed as a result of the reaction between two monosaccharides releasing a water molecule whereas peptide bonds are formed as a result of the reaction between two amino acids releasing a water molecule.
Therefore, these are condensation or dehydration synthesis reactions.

What is Hydrolysis Hydrolysis is cleavage of a chemical bond in the presence of water. Here, water act as a reactant that is involved in the reaction process. In hydrolysis reactions, a large molecule is always broken down into smaller molecules.
Therefore, the reactants always include a complex molecule, unlike products. In these reactions, a water molecule is added to the reactant molecule, which causes the cleavage of a chemical bond present in that reactant. When a large molecule is hydrolyzed, the resulting two small molecules get a —OH group and a —H group from the water molecule. Hydrolysis is the opposite of condensation. This is because, in condensation reactions, a water molecule is formed whereas in hydrolysis a water molecule is consumed.
Ester Hydrolysis Reaction If we take the same example as in dehydration synthesis reaction, hydrolysis of an ester forms the reactants of esterification reaction.
