Condensation Condensation is the conversion of vapor to liquid. It occurs when the air becomes saturated with moisture and releases it in the form of water. It is recognized by the wet mist that sometimes clouds the interior glass on your homes windows.

Difference Between Hydrolysis and Condensation Condensation reactions are a type of chemical reaction where small molecules get together to form a large single molecule. The reaction takes place within two functional groups in the molecules. Other characteristic feature of a condensation reaction is that a small molecule is lost during the reaction.

Condensation Condensation is initiated by the formation of atomic/molecular clusters of that species within its gaseous volume—like rain drop or snow flake formation within clouds —or at the contact between such gaseous phase and a liquid or solid surface.

Condensation Polymerization When a carboxylic acid and an alcohol react, a water molecule is removed, and an ester molecule is formed. Because of this ester formation, this bond is known as an ester linkage. Monomers involved in condensation polymerization have functional groups. These functional groups combine to form amide and ester linkages. When this occurs, a water molecule in removed. Since water is removed, we call these reactions condensation reactions (water condenses out.). When a condensation reaction involves polymerization, we call it condensation polimarization. Let's look at a few common examples of condensation polymers.

DNA condensation DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo.[1] Mechanistic details of DNA packing are essential for its functioning in the process of gene regulation in living systems. Condensed DNA often has surprising properties, which one would not predict from classical concepts of dilute solutions.

An Introduction to Molecular Biology/Function and structure of Proteins From Wikipedia, the free encyclopedia. The condensation of two amino acids to form a peptide bond (red) with expulsion of water (blue). A condensation reaction, is a chemical reaction in which two molecules or moieties (functional groups) combine to form a larger molecule, together with the loss of a small molecule.f the union is between atoms or groups of the same molecule, the reaction is termed intramolecular condensation, and in many cases leads to ring formation.

- Condensation. The process of water changing from a vapor to a liquid. Water vapor in the air rises mostly by convection. This means that warm, humid air will rise, while cooler air will flow downward. As the warmer air rises, the water vapor will lose energy, causing its temperature to drop. The water vapor then has a change of state into liquid or ice.

DNA condensation Condensation of long double-helical DNAs is a sharp phase transition, which takes place within a narrow interval of condensing agent concentrations.[ref] Since the double helices come very closely to each other in the condensed phase, this leads to the restructuring of water molecules, which gives rise to the so-called hydration forces.[ref] To understand attraction between negatively charged DNA molecules, one also must account for correlations between counterions in the solution.[ref] DNA ...

Condensation reaction Condensation reaction. Written By: Condensation reaction, any of a class of organic reactions in which two molecules combine, usually in the presence of a catalyst, with elimination of water or some other simple molecule. The combination of two identical molecules is known as self-condensation.

Hydrolysis/Condensation Reactions used in building macromolecules. two molecules joined together to form larger molecule. water is formed in reaction. example: two amino acids can be joined to form a di-peptide joined by a peptide linkage (bond) Condensation reaction can also be used to build up: carbohydrates, lipids.

- Aldol Condensation. The aldol condensation is a reaction in which aldehydes and ketones react to form larger molecules. A new carbon-carbon bond is formed. In this generalized reaction the a-carbon of one aldehyde forms a bond with the carbonyl carbon of the other aldehyde.ldehydes and ketones have higher melting and boiling points than hydrocarbons of equivalent molecular weight. This is due to the attraction between molecule due to the polarity of the carbonyl group.

- In one type of polymerization reaction, a series of condensation steps take place whereby monomers or monomer chains add to each other to form longer chains. This is termed 'condensation polymerization' or ' step-growth polymerization ', and occurs for example in the synthesis of polyesters or nylons.

Condensation Condensation forming in the low pressure zone above the wing of an aircraft due to adiabatic expansion. Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of evaporation. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapour to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere.

Condensation polymer Condensation polymers are any kind of polymers formed through a condensation reaction —where molecules join together— losing small molecules as by-products such as water or methanol, as opposed to addition polymers which involve the reaction of unsaturated monomers.

Carbonyl Condensation Reactions The aldol condensation is a reaction that occurs between two aldehyde or ketone molecules. Aldol reactions are reversible – initially producing β-hydroxy aldehydes/ketones and then α,β-unsaturated products after dehydration.

- The aldol condensation is an important reaction in organic chemistry, primarily because this reaction is one of a limited number of reactions that result in the formation of a new carbon-carbon bond.This reaction is also relevant to biochemistry.echanism. In the first step of the aldol condensation, a strong base reacts with the a-hydrogen to produce a negatively-charged (and very reactive) carbon atom. This reactive molecule is referred to as a nucleophile (nucleus loving).

The Chemistry of Weather: Condensation and Evaporation Condensation is the process by which water residing in the air changes from water vapor (a gas) to liquid water. This happens when the water vapor is cooled to the dew point temperature, which leads to saturation. Anytime you have warm air rising up into the atmosphere, you can expect condensation to eventually occur.

Condensation - The Water Cycle Water cycle for kids poster. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle. Condensation is the opposite of evaporation.
