What is the product of the condensation of two monosaccharides?
A condensation reaction between two monosaccharides forms a glycosidic bond. Disaccharides are formed by the condensation of two monosaccharides: maltose is a disaccharide formed by condensation of two glucose molecules. sucrose is a disaccharide formed by condensation of a glucose molecule and a fructose molecule.
What are 2 monosaccharides join together?
Disaccharides (di- = “two”) form when two monosaccharides join together via a dehydration reaction, also known as a condensation reaction or dehydration synthesis.
Which sugar is not a reducing sugar?
Sucrose
Sucrose is one example of a non-reducing sugar.
How are two monosaccharides bonded in a condensation reaction?
The two monosaccharides are bonded via a dehydration reaction (also called a condensation reaction or dehydration synthesis) that leads to the loss of a molecule of water and formation of a glycosidic bond. The glycosidic bond can be formed between any hydroxyl group on the component monosaccharide.
How are monosaccharides classified according to their properties?
Monosaccharides are classified according to three different characteristics: the location of their carbonyl group, the number of carbon atoms they contain, and their chiral property. If the carbonyl group is an aldehyde, the monosaccharide is an aldose.
Which is the smallest monosaccharide with three carbon atoms?
If the carbonyl group is an aldehyde, the monosaccharide is an aldose. If the carbonyl group is a ketone, the monosaccharide is a ketose. Monosaccharides with three carbon atoms are called trioses and these are the smallest monosaccharides, such as dihydroxyacetone and d – and l -glyceraldehyde.
How are disaccharides formed in a dehydration reaction?
Formation Disaccharides are formed when two monosaccharides join together by the dehydration synthesis reaction resulting in a glycosidic bond between the two monosaccharide molecules. The reaction produces water as a side product. Made of many (hundreds or thousands) monosaccharides joined by covalent bonds.
