2.1.2: Condensation And Hydrolysis Reactions

Question 1

What is a condensation reaction in the context of biological molecules?

Answer 1

A condensation reaction creates a disaccharide by removing a water molecule from the hydroxyl groups of two monosaccharides, forming a glycosidic bond

The glycosidic bond formed can be specifically a 1-4 glycosidic bond when it occurs between carbon 1 and carbon 4.

Question 2

What is the function of a glycosidic bond?

Answer 2

A glycosidic bond links monosaccharides together to form disaccharides and polysaccharides

It is formed during a condensation reaction.

Question 3

What happens during a hydrolysis reaction?

Answer 3

A hydrolysis reaction breaks down disaccharides into monosaccharides by adding water, which breaks the glycosidic bond

The water molecule that was removed during condensation is added back in.

Question 4

Fill in the blank: A _______ reaction creates a disaccharide by removing a water molecule.

Answer 4

[condensation]

Question 5

True or False: Hydrolysis reactions can only occur in the presence of heat.

Answer 5

False

Question 6

What is the result of adding water during a hydrolysis reaction?

Answer 6

The glycosidic bond is broken, resulting in the formation of monosaccharides

This process essentially reverses the condensation reaction.

Question 7

What type of bond is formed between two monosaccharides during a condensation reaction?

Answer 7

Glycosidic bond

Question 8

What is the significance of the 1-4 glycosidic bond?

Answer 8

It specifies the linkage between carbon 1 and carbon 4 of the monosaccharides involved

This specific positioning is important for the structure and function of the resulting disaccharide.
