What type of reaction allows the glucose molecules to bond with one another?
In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.
What is a dehydration condensation reaction?
In chemistry, a dehydration reaction, also known as Zimmer’s Hydrogenesis, is a chemical reaction that involves the loss of water from the reacting molecule or ion. It is the most common type of condensation reaction. Dehydration reactions are common processes, the reverse of a hydration reaction.
What is the reaction that links two monosaccharides together?
dehydration reaction
Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. Sucrose (table sugar) is the most common disaccharide, which is composed of the monomers glucose and fructose.
What kind of reaction would be needed to break apart glucose and fructose?
Hydrolysis
Hydrolysis is used to break the bond between glucose and fructose in the molecule sucrose.
What forms when two monosaccharides are covalently bonded together?
Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. Sucrose (table sugar) is the most common disaccharide, which is composed of the monomers glucose and fructose.
What are the chemical reaction of monosaccharides?
identify the product formed when a given monosaccharide is reacted with acetic anhydride or with silver oxide and an alkyl halide….Reduction.

Which two compounds react together to form a condensation polymer?
They arise from the reaction of carboxylic acid and an amine. Examples include nylons and proteins.
What is formed when two glucose molecules are dehydrated?
In the dehydration synthesis reaction between two molecules of glucose, a hydroxyl group from the first glucose is combined with a hydrogen from the second glucose, creating a covalent bond that links the two monomeric sugars (monosaccharides) together to form the dissacharide maltose.
What is the role of glucose in chemical reaction?
Glucose Chemical Reaction Glucose is an indispensable nutrient for metabolism in the body. The heat released by its oxidation reaction is an important source of energy required for human life activities. It can be used directly in the food and pharmaceutical industries. It is used as a reducing agent in the dyeing and tanning industry.
Why is dehydration synthesis called a condensation reaction?
In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water. ” It is also considered to be a condensation reaction since two molecules are condensed into one larger molecule with the loss of a smaller molecule (the water.)
What is the chemical equation for the hydrolysis of glucose?
CH2OH (CHOH)4CHO + 2Cu (OH)2 – heating -> CH2OH (CHOH)4 of COOH + aCu2O ↓ + 2H2O. (8) Glucose is decomposed into water and carbon dioxide under certain conditions. (9) Hydrolysis of maltose:
