In the category of carbohydrates, there are monosaccharides, disaccharides, oligosacchaides, and polysaccharides. Just from the prefixes, you can tell that the monosaccharides are monomers, the disaccharides are two bonded monomers (monosaccharides) and oligosacchaides and polysaccharides are made up of many monomers (monosaccharides).
The monosaccharides are just a single carbon ring (in the natural aqueous environment of an organism). The monosaccharides include glucose, fructose, and galactose. The disaccharides are two carbon rings bonded together by a glycosidic linkage in a condensation (dehydration) reaction, which removes a molecule of water. Disaccharides include maltose (glucose + glucose), lactose (glucose + galactose), sucrose (glucose + fructose), and more.
When we consume food, we are taking in the large polysacchaides such as starch and smaller molecules such as maltose. We take these long molecules and digest them - break up their glycosidic linkages until they are monosaccharides (monomers) that we can absorb throughout out alimentary canal (usually in small intestine).
A monosaccharide is one saccharide (or sugar) molecule. An example of a monosaccharide is glucose.
A disaccharide is two saccharides (sugars) bonded together through a dehydration reaction. An example of a disaccharide is maltose which is two glucose linked together.
A polysaccharide is typically ten or more saccharides bonded together. Cellulose is an example of a polysaccharide, which is ten or more glucose linked together.
What else can I help you with?
What molecule is formed when many disaccharides are combined?
A Polysaccharide.
What are the three basic structures of a carbohydrate?
Monosaccharide , Disaccharide, Polysaccharide
Why must disaccharides and polysaccharide be digested before an organism can use them?
Because organisms use (metabolize) monosaccarides.
How does polysaccharide differ from disaccharide?
Disaccharides have only 2 molecules of sugar while polysaccharides have more then 15
Explain the difference between disaccharide and a polysaccharide?
a disaccharide is two monosaccharides. and a polysaccharide is a long chain of monosaccharides joined together. they are units of carbohydrates.
What are the monosaccharides and disaccharides in amylose and cellulose?
The monosaccharide in both amylose and cellulose is glucose. However, amylose is a polysaccharide made up of long chains of glucose units linked by alpha-1,4-glycosidic bonds, while cellulose is also a polysaccharide made up of long chains of glucose units linked by beta-1,4-glycosidic bonds. Disaccharides are not typically found in these polysaccharides.
What are the differences between a monoscaccharide a disccharide and a polysaccharide?
Polysaccharides = one sugar, such as glucose Disaccharides = linked sugars--two glucose forming maltose. Polysaccharides = many linked sugars--starch is an example of this.
What happens when you heat polysaccharides?
If a polysaccharide is heated in a strong acid medium, the covalent glycosid bonds break through hydrolysis, creating disaccharides. Later on the reaction continues with the disaccharides, ending the reaction with nothing but monosacharides (Glucose, fructose etc.)
How can you tell by using iodine if a sugar is a monosaccharide disaccharide or polysaccharide?
Adding iodine to the solution will turn it a deep blue which indicate presence of polysaccharides.
Which enzyme will help you hydrolyze polymers into disaccharides or monomers after eating carbohydrates?
The most common enzyme would be salivary/pancreatic amylase which hydrolyzes the polysaccharide amylose.
What do monosaccharides combine to make?
Monosaccharides combine to make disaccharides or polysaccharides through a dehydration synthesis reaction, where a water molecule is released. Examples of disaccharides include sucrose (glucose + fructose) and lactose (glucose + galactose). Examples of polysaccharides include starch, glycogen, and cellulose.
How does a polysaccharide differ from a disaccharide?
A polysaccharide is a complex carbohydrate made up of multiple monosaccharide units linked together, while a disaccharide is made up of two monosaccharide units linked together. Polysaccharides are larger molecules and are used for energy storage and structural support, while disaccharides are smaller and are primarily used for energy transport.
