Condensation is a chemical process by which 2 molecules are joined together to make a larger, more complex, molecule, with the loss of water.
It is the basis for the synthesis of all the important biological macromolecules (carbohydrates, proteins, lipids, nucleic acids) from their simpler sub-units.
It is important not to get condensation and hydrolysis muddled up, as they are in fact opposite processes! Condensation is so called because the product is drawn together from two other substances, in effect getting smaller by losing water. It does not give off water to condense and run down the window!
In all cases of condensation, molecules with projecting -H atoms are linked to other molecules with projecting -OH groups, producing H2O, ( H.OH ) also known as water, which then moves away from the original molecules.
A-H + B-OH --> A-B + H2O
Dehydration Synthesis
A hydrolysis reaction. Water is added. Dehydration synthesis is when two water molecules join together. Hydrolysis is the separation of two water molecules.
The nucleotide that supplies energy for dehydration synthesis is adenosine triphosphate (ATP). ATP releases energy when its terminal phosphate group is cleaved in a hydrolysis reaction, providing energy for bond formation during dehydration synthesis.
Monosaccharides are produced through the hydrolysis of polysaccharides, a reaction where water is added to break the glycosidic bonds linking sugar units together. This process results in the cleavage of the polymer into individual monosaccharide units. On the other hand, dehydration synthesis (or condensation) of monosaccharides forms polysaccharides by removing water to create glycosidic bonds.
Monomers are not joined together by the process of hydrolysis. Dehydration synthesis, or condensation reaction is the process of chemically joining monomers.

In chemistry, condensation reactions are when covalent bonds are formed between molecules and a water molecule is generated as a byproduct. The reverse of this process is hydrolysis, whereby water is consumed in order to cleave a covalent bond.
The reverse of dehydration synthesis is hydrolysis, a chemical reaction that breaks down molecules by adding water. In hydrolysis, a water molecule is split into a hydrogen ion and a hydroxide ion, which are added to the molecule being broken down.
Dehydration synthesis cannot be reversed directly. To break down the molecules formed during dehydration synthesis, a hydrolysis reaction is required. This involves adding water to break the bonds between the molecules and return them to their original components.
Hydrolysis converts polymers to monomers by adding H2O between each monomer. In dehydration synthesis, the opposite occurs. As the name implies, water is removed in order to bond the monomers.

A dehydration reaction involves removing a water molecule to form a bond between two molecules, while a hydrolysis reaction breaks a bond between two molecules by adding a water molecule. Dehydration reactions are involved in building macromolecules like proteins and carbohydrates, while hydrolysis reactions are involved in breaking down these macromolecules for energy or recycling.
