When Biological Molecules Engage In Condensation Such Reactions Are?

Condensation is the formation of larger biological molecules (polymers) from smaller molecules (monomers), with the byproduct being water. These biomolecular condensates are found throughout eukaryotic cells, including in the nucleus, cytoplasm, and on membranes. They play a vital role in physiological and cellular functions.

Theoretical concepts from polymer and physical chemistry provide a mechanistic framework for understanding the behavior of multivalent molecules. Acetyl coenzyme A is an important biomolecule that undergoes carbonyl condensation reactions, while aldoases are enzymes that catalyze aldol reactions in biomolecular condensates.

Biomolecular condensates are micron-scale compartments in eukaryotic cells that lack surrounding membranes but concentrate biomolecules, including proteins and nucleic acids. These membraneless intracellular assemblies often form via liquid-liquid phase separation and have the ability to concentrate.

Drug molecules can exploit condensate properties to concentrate in the same compartment as their target, potentially enhancing their pharmacological properties. Condensation reactions involve the combination of large numbers of monomers to form a large macro molecule, with water molecules being released during the reaction.

Dehydration or condensation reactions are chemical reactions in which monomers (small molecules) join together to form polymers (large molecules or macromolecules). Proteins are polymers made up of amino acid monomers, and the loss of water molecules can occur due to reactions between two functional groups like –OH, -NH2, or –COOH.

What is an example of a condensation reaction?

Many variations of condensation reactions exist. Common examples include the aldol condensation and the Knoevenagel condensation, which both form water as a by-product, as well as the Claisen condensation and the Dieckman condensation (intramolecular Claisen condensation), which form alcohols as by-products.5.

Synthesis of prebiotic moleculesedit. Condensation reactions likely played major roles in the synthesis of the first biotic molecules including early peptides and nucleic acids. In fact, condensation reactions would be required at multiple steps in RNA oligomerization: the condensation of nucleobases and sugars, nucleoside phosphorylation, and nucleotide polymerization.6.

What is condensation in the biological system?

In biology the term condensation is used much more broadly and can also refer to liquid–liquid phase separation to form colloidal emulsions or liquid crystals within cells, and liquid–solid phase separation to form gels,1 sols, or suspensions within cells as well as liquid-to-solid phase transitions such as DNA condensation during prophase of the cell cycle or protein condensation of crystallins in cataracts.18 With this in mind, the term biomolecular condensates was deliberately introduced to reflect this breadth (see below). Since biomolecular condensation generally involves oligomeric or polymeric interactions between an indefinite number of components, it is generally considered distinct from formation of smaller stoichiometric protein complexes with defined numbers of subunits, such as viral capsids or the proteasome – although both are examples of spontaneous molecular self-assembly or self-organisation.

Mechanistically, it appears that the conformational landscape56 (in particular, whether it is enriched in extended disordered states) and multivalent interactions between intrinsically disordered proteins (including cross-beta polymerisation),57 and/or protein domains that induce head-to-tail oligomeric or polymeric clustering,58 might play a role in phase separation of proteins.

Many examples of biomolecular condensates have been characterized in the cytoplasm and the nucleus that are thought to arise by either liquid–liquid or liquid–solid phase separation.

What biomolecules are formed by condensation reactions?

Answer and Explanation: Polypeptides, polysaccharides, and nucleic acids are produced via condensation reactions (see reaction schemes below) where a water molecule is formed as a by-product.

What is an example of a condensation reaction in biology?

Polypeptide and Polynucleotide Synthesis. Amino acids can condense into polypeptide molecules (proteins), releasing water as a byproduct. Also, DNA and RNA are made via polynucleotide synthesis which is also a condensation reaction. Polynucleotides form when the phosphate group on one nucleotide molecule reacts with the hydroxyl group on the carbohydrate group of another nucleotide. During this reaction, a water molecule is formed and released.

The image above shows polynucleotide synthesis using the amine group (red) of one amino acid and the carboxyl group (red) of another amino acid. The condensation reaction forms a water molecule (blue).

Nylon. Nylon is a man-made condensation polymer, meaning several identical molecular units are attached together using a condensation reaction. Nylon 66, one of the most important types of nylon, is made from adipic acid and hexamethylenediamine. The nylon polymer is formed by binding the amine groups on the hexamethylenediamine to the carboxylic acid groups on the adipic acid molecules in an alternating pattern. The byproduct of this condensation reaction is water.

What happens when a condensation reaction occurs?

In a condensation reaction, two (or more) molecules combine to form a single molecule. A small molecule, often water, is usually removed during a condensation reaction.Amino acids are important biological molecules that have an amine functional group on one end of the molecule and a carboxylic acid functional group on the other end. When two amino acids combine in a condensation reaction, a covalent bond forms between the carboxyl carbon of one amino acid and the amine nitrogen of the second amino acid. A molecule of water is then removed as a second product.

This reaction forms a molecule called a dipeptide and the carbon-nitrogen covalent bond is called a peptide bond or amide bond.When repeated numerous times, a long molecule called a protein is eventually produced.

Esterification. An esterification reactionis a condensation reaction in which reactants (typically an alcohol and carboxylic acid)combine to produce an ester.

What are 3 examples of condensation reaction?

Few examples of condensation are given below: Morning dew on the grass. Water droplets on the outer surface of cold drink bottle. Foggy car windows.

Commercial applications of condensation, by consumers as well as industry, include power generation, water desalination, thermal management, refrigeration, and air conditioning.

Condensates form when their vapor pressure is lowered to the point that the natural gas liquids condense out of the gas stream into a liquid that can be stored at room temperature.

What are 4 examples of condensation?

• What are some examples of condensation?Coming up with examples of condensation is a bit harder than examples of evaporation. One common example is water that forms on the outside of a cold cup or the moisture that forms on car windows during a cool night. Other examples of condensation are dew, fog, clouds, and the fog you see when you breathe out on a cold day.
• You may have made a cold window “cloudy” by breathing on it and then drawn on the window with your finger. Where do you think that cloudiness comes from?Help students realize that the moisture on the window, and all of the examples of condensation they gave, comes from water vapor in the air.
• A real cloud is made up of tiny droplets of water. Where do you think they come from?The water in a cloud comes from water vapor in the air that has condensed.

What is condensation reaction in molecular biology?

Condensation Reactions. A condensation reaction is a reaction in which two molecules combine to form a single molecule. A small molecule, often water, is usually removed during a condensation reaction. Amino acids are important biological molecules that have an amine functional group on one end of the molecule and a carboxylic acid functional group on the other end. When two amino acids combine in a condensation reaction, a covalent bond forms between the amine nitrogen of one amino acid and the carboxyl carbon of the second amino acid. A molecule of water is then removed as a second product.

This reaction forms a molecule called a dipeptide and the carbon-nitrogen covalent bond is called a peptide bond. When repeated numerous times, a lengthy molecule called a protein is eventually produced.

Esterification. An esterification is a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid. Esterification is a subcategory of condensation reactions because a water molecule is produced in the reaction. The reaction is catalyzed by a strong acid, usually sulfuric acid. When the carboxylic acid butanoic acid is heated with an excess of methanol and a few drops of sulfuric acid, the ester methyl butanoate is produced. Methyl butanoate has the scent of pineapples. The reaction is shown below with both molecular and structural formulas.

What reactions are involved in the condensation reaction?

15.9 Condensation Polymers. A condensation reaction is a reaction between two reactants that yields one larger product and a second, smaller product such as water. This type of reaction has been illustrated in the reactions of many functional groups containing oxygen or nitrogen. Products of condensation reactions include ethers, acetals, esters, imines, and amides.

We now consider condensation reactions that yield polymers. Two functional groups are required in a monomer so that after one functional group reacts, the other is available to link to another monomer. The functional groups in monomers may be arranged in two ways for condensation polymerization.

A single compound can contain two different functional groups such as an amino group and a carboxylic acid group. Reaction of the amino group of one molecule with the carboxylic acid of another molecule gives an amide that still has a free amino group and a free carboxylic acid group, which can continue to react to form a polymer. The general reaction is shown below.

Which type of reactions occur when biological molecules engage in condensation?

Hydrolysis Reactions. The classification of hydrolysis reactions include both the forward reactions that involve the addition of water to a molecule to break it apart or the reverse reaction involving the removal of water to join molecules together, termed dehydration synthesis (or condensation) (Figure 7.7). When water is added to a molecule to break it apart into two molecules this reaction is called hydrolysis. The term ‘lysis‘ means to break apart, and the term ‘hydro‘ refers to water. Thus, the term hydrolysis means to break apart with water. The reverse of that reaction involves the removal of water from two molecules to join them together into a larger molecule. Since the two molecules are losing water, they are being dehydrated. Thus, the formation of molecules through the removal of water is known as dehydration synthesis. Since water is also a by-product of these reactions, they are also commonly referred to as condensation reactions. As we have seen in Chapter 6, the formation of the major classes of macromolecules in the body (proteins, carbohydrates, lipids, and nucleic acids) are formed through dehydration synthesis where water is removed from the molecules (Figure 7.x). During normal digestion of our food molecules, the major macromolecules are broken down into their building blocks through the process of hydrolysis.

Figure 7.7 Hydrolysis and Dehydration Synthesis. The reactions of hydrolysis mediate the breakdown of larger polymers into their monomeric building blocks by the addition of water to the molecules. The reverse of the reaction is dehydration synthesis, where water is removed from the monomer building blocks to create the larger polymer structure.

As you learned in Chapter 6, the major macromolecules are built by putting together repeating monomer subunits through the process of dehydration synthesis. Interestingly, the organic functional units used in the dehydration synthesis processes for each of the major types of macromolecules have similarities with one another. Thus, it is useful to look at the reactions together (Figure 7.8)
