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
