Condensation reactions occur naturally in biological and chemical processes on Earth or synthetically by man-made means. If a condensation reaction happens between various parts of the same molecule, it is called intramolecular condensation. A condensation reaction that occurs between two separate molecules is called intermolecular condensation.
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.
Condensation Definition. Condensation has multiple meanings in the field of biology. A condensation reaction is when two smaller molecules join to form a larger one by removing functional groups that form a small molecule, often water.Condensation can also refer to a state change in water from gas to liquid, which is an important step in the water cycle.

A condensation reaction is a class of organic addition reaction that typically proceeds in a step-wise fashion to produce the addition product, usually in equilibrium, and a water molecule (hence named condensation).The reaction may otherwise involve the functional groups of the molecule, and formation of a small molecule such as ammonia, ethanol, or acetic acid instead of water.
Condensation reactions form all the biological macromolecules that we know, such as, proteins, fats, nucleic acid and carbohydrates. Below is an animation showing the reaction between two amino acids to form a dipeptide. Amino acids join end to tend to form proteins. At the fomation of each peptide llink a water molecule is expelled.
A condensation reaction is a chemical reaction between two compounds where one of the products is water, ethanol, acetic acid, hydrogen sulfide, or ammonia.A condensation reaction is also known as a dehydration reaction.This type of reaction forms an addition product and water in the presence of a catalyst or under acidic or basic conditions.
An example is the Dieckmann condensation, in which the two ester groups of a single diester molecule react with each other to lose a small alcohol molecule and form a β-ketoester product. Many condensation reactions follow a nucleophilic acyl substitution or an aldol condensation reaction mechanism (see previous concept for more information).
Mechanism; Condensation Types; An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone, followed by dehydration to give a conjugated enone.. Aldol condensations are important in organic synthesis, because they provide a good way to form carbon–carbon bonds.
