Condensation reaction in polypeptide formation involves the removal of a water molecule as amino acids link together through peptide bonds. Specifically, the carboxyl group of one amino acid reacts with the amino group of another, forming a peptide bond and releasing a water molecule as a byproduct. This process is repeated sequentially to form a chain of amino acids, resulting in the formation of a polypeptide.
Two amino acids condense by forming a peptide bond via a condensation reaction. A H is lost from an amino acid's amine group while a hydroxyl group is lost from the other amino acid's carboxyl group.
The amino acids formed can join together to form proteins of any lengths.

Why doesn't ninhydrin react with polypeptides?
Ninhydrin does react with polypeptides, specifically with the amino group of amino acids present in the polypeptide chain. This reaction leads to the formation of a colored compound that can be used for detection and analysis of amino acids and polypeptides.
Define the type of chemical reaction involved in the formation of a peptide linkage between two amino acids and state the other product in addition to a dipetide?
The formation of a peptide linkage between amino acids is a condensation reaction, specifically a dehydration synthesis reaction. The other product in addition to the dipeptide is a molecule of water.
Why aldol condensation is called condensation reaction?
Aldol condensation is called a condensation reaction because it involves the removal of a molecule of water. In this reaction, two molecules, typically containing carbonyl groups, combine with the loss of a water molecule to form a new compound. The term "condensation" refers to the release of water during the reaction process.
What is an example Condensation reaction?
An example of a condensation reaction is the formation of a peptide bond between two amino acids during protein synthesis. This reaction involves the loss of a water molecule and the joining of the amino acids to form a dipeptide.
What chemical reaction form polysaccharides?
Polysaccharides are formed through condensation reactions between monosaccharide units. These reactions involve the removal of a water molecule as two monosaccharides join together to form a glycosidic bond. This process is catalyzed by enzymes and results in the formation of long chains of polysaccharides.
What chemical reaction is used to synthesize macromolecules like polypeptides and starch?
The chemical reaction used to synthesize macromolecules like polypeptides and starch is called dehydration synthesis or condensation reaction. This reaction involves joining monomers together by removing a water molecule to form a covalent bond between them.
Why doesn't ninhydrin react with polypeptides?
Ninhydrin does react with polypeptides, specifically with the amino group of amino acids present in the polypeptide chain. This reaction leads to the formation of a colored compound that can be used for detection and analysis of amino acids and polypeptides.
How are polypeptides held together?
Polypeptides are held together by peptide bonds, which are formed through a condensation reaction between the amino group of one amino acid and the carboxyl group of another. These bonds link amino acids together to form a linear chain, which is the primary structure of a protein.
Is claisen condensation a condensation reaction?
Of course,The Claisen Condensation is typically the reaction between two esters, in the presence of base, leading to formation of an ester enolate that reacts with an uncharged ester, thereby displacing it's "alcohol part" as the leaving group. The sequence leads to the formation of beta ketoesters. The intramolecular (cyclic) version of the Claisen Condensation is known as the Dieckmann Condensation, and is illustrated through the article, "Dieckmann Condensation Missing Piece."
Define the type of chemical reaction involved in the formation of a peptide linkage between two amino acids and state the other product in addition to a dipetide?
The formation of a peptide linkage between amino acids is a condensation reaction, specifically a dehydration synthesis reaction. The other product in addition to the dipeptide is a molecule of water.
Why aldol condensation is called condensation reaction?
Aldol condensation is called a condensation reaction because it involves the removal of a molecule of water. In this reaction, two molecules, typically containing carbonyl groups, combine with the loss of a water molecule to form a new compound. The term "condensation" refers to the release of water during the reaction process.
Is a condensation reaction an anabolic reaction?
Yes, a condensation reaction is an anabolic reaction. It involves the formation of larger molecules from smaller ones by the removal of a water molecule. This process is common in the synthesis of complex molecules like proteins and carbohydrates.
What are the products of a condensation reaction between glucose and fructose?
The products of a condensation reaction between glucose and fructose are sucrose and water. In this reaction, a glycosidic bond forms between the glucose and fructose molecules, resulting in the formation of the disaccharide sucrose. Water is also produced as a byproduct of the condensation reaction.
What is an example Condensation reaction?
An example of a condensation reaction is the formation of a peptide bond between two amino acids during protein synthesis. This reaction involves the loss of a water molecule and the joining of the amino acids to form a dipeptide.
What is the name of the reaction in which two hexose sugars combine to form a disaccharide?
The reaction is called a condensation reaction, specifically a glycosidic bond formation. Two hexose sugars combine with the removal of a water molecule to form a disaccharide.
What type of reaction results in the formation of all macromolecules?
Condensation reactions result in the formation of all macromolecules. In condensation reactions, two molecules combine to form a larger molecule, with the elimination of a smaller molecule such as water. This process is commonly observed in the polymerization of macromolecules like proteins, nucleic acids, and carbohydrates.
Compare the process used in the formation of a dipeptide and a disaccharide?
In the formation of a dipeptide, two amino acids undergo a condensation reaction, where the carboxyl group of one amino acid reacts with the amino group of another amino acid, forming a peptide bond and releasing a molecule of water. In the formation of a disaccharide, two monosaccharides undergo a condensation reaction, where the hydroxyl group of one monosaccharide reacts with the anomeric carbon of another monosaccharide, forming a glycosidic bond and releasing a molecule of water.
