1
Q
disaccharides
A
- formed from the linkage of two monosaccharides together in a process called dehydration synthesis.
- made when two monosaccharides are bonded together in a process called dehydration synthesis.
Dehydration synthesis is the process by which an –OH from one monosaccharide and a hydrogen from the other are removed to form one molecule of water. In this example, two glucose molecules bond to form the
disaccharide maltose. The bond between monosaccharides is called a glycosidic linkage.
2
Q
hydrolysis
A
- a disaccharide can be separated into two monosaccharides
3
Q
monomer
A
- Polymers are long molecules made from many
subunits bonded together like beads on a
string. Each subunit is called a monomer.
4
Q
monosaccharides
A
- such as glucose, are a major energy source for the cell. They are put into storage by being linked together to form polymers.
5
Q
hydrolysis
A
- reverse reaction of a dehydration synthesis also takes place
- one water molecule is used to break a glycosidic linkage. In this process, the water molecule itself is broken.
6
Q
Maltose is
A
- a disaccharide that consists of two glucose molecules
7
Q
True or false?
The formation of a disaccharide from two monosaccharides is considered a hydrolysis because water is split in the process.
A
- false
8
Q
True or false?
Disaccharides are formed by a process called dehydration synthesis.
A
- true
9
Q
Which of the following are examples of monosaccharides?
A
- glyceraldehyde and galactose
10
Q
__________ is a reaction in which two monomers are joined to form a macromolecule and water is released as a byproduct.
A
- Dehydration synthesis
11
Q
Sucrose is formed from glucose and fructose by __________. In this process, water is __________.
A
- dehydration, formed
12
Q
The production of glucose and fructose from sucrose could be accomplished by __________. In this process, water would be __________.
A
- hydrolysis, consumed
