Monomers and Polymers

Question 1

what bond forms between the two glucose molecule?

Answer 1

1,4 - glycosidic bond

Question 2

What is a condensation?

Answer 2

• covalent bonds form between monomers,
• allowing them to join together into polymers.
• As these bonds form, water molecules are removed (or lost)

Question 3

What is hydrolysis?

Answer 3

• breaks lactose down by breaking glyosidic bonds between galactose and glucose.
• Water is added to the reaction.

Question 4

How a peptide bond forms between two amino acids.

Answer 4

• A peptide bond forms between two amino acids in a condensation reaction. The bond forms between the carboxyl group of one amino acid and the amine group of the other. This is a condensation reaction, where two molecules react to form one, joined by a bond and includes the removal of water. The bond is called a peptide bond.

Question 5

Explain the structure of an amino acid ?

Answer 5

An amino acid is made up of four groups bonded to a central carbon atom. These groups include a hydrogen atom, a carboxyl group, an amine group and a R group. The R group differs for each amino acid.

Question 6

What is a disaccharide?

Answer 6

• formed when 2 monosaccharides form a glyosidic bond (chemical bond which joins two hexose units together) in a condensation reaction
