Are raffinose and stachyose examples of polysaccharides?
Table of Contents
Complex Carbohydrates Examples are raffinose and stachyose. Polysaccharides are often made up of a large number of monosaccharides and disaccharides. Examples are starch, glycogen and cellulose.
Is raffinose a monosaccharide disaccharide or polysaccharide?
Oligosaccharides are carbohydrates made up of a small number of monosaccharide units and are relatively smaller than polysaccharides. An example of an oligosaccharide is raffinose. Raffinose is a trisaccharide, meaning it is made up of three monomers of monosaccharides, namely galactose, glucose, and fructose.
Is raffinose a monosaccharide?
Raffinose is a trisaccharide in which glucose acts as a monosaccharide bridge between galactose and fructose. It has both α and β glycosidic bonds and can therefore be hydrolyzed to d-galactose and sucrose via enzymes with α-glycosidic activity, and to melibiose and d-fructose via enzymes with β-glycosidic activity.
What are examples of monosaccharides and polysaccharides?
Explanation: Glucose, fructose, sucrose, galactose etc., are the monosaccharides, while the glycogen, cellulose, starch etc., are polysaccharides. Polysaccharides are long chains of monosaccharides bound by glycosidic linkage.
What are the monosaccharides that compose raffinose?
Raffinose is a trisaccharide composed of galactose, glucose, and fructose.
What is stachyose made of?
Stachyose is a tetrasaccharide consisting of sucrose having an alpha-D-galactosyl-(1->6)-alpha-D-galactosyl moiety attached at the 6-position of the glucose. It has a role as a plant metabolite and a mouse metabolite.
How many monosaccharides make up a polysaccharide?
As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units; but the precise cutoff varies somewhat according to convention. Polysaccharides are an important class of biological polymers.
Is raffinose a disaccharide?
Since it contains 3 monosaccharide units, Raffinose is a trisaccharide. It provides glucose + fructose + galactose upon hydrolysis. It is primarily found in beans, cabbage, brussels sprouts, broccoli, asparagus, and also in whole grains.
What is the formula of stachyose?
C24H42O21Stachyose / Formula
What are lipids monomers?
Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats.
What are monosaccharides disaccharides and polysaccharides?
One monosaccharide serves as the acetal or ketal center that reacts with the hydroxyl group of the next monosaccharide. Disaccharides are oligosaccharides that contain two monosaccharide units. Polysaccharides contain a large number of monosaccharide units bonded to each other by a series of glycosidic bonds.
What are the hydrolysis product of stachyose?
A tetrasaccharide is a carbohydrate which gives upon hydrolysis four molecules of the same or different monosaccharides. For example, stachyose upon hydrolysis gives one molecule each of glucose and fructose and two molecules of galactose.
