Polymers

A chain of repeating units (called monomers)

• monomer

• dimer

• replicate

• polymer

A polymer made in the laboratory (or industry) usually made from petrochemicals

• nature polymer

• natural polymer

• protein

• synthetic polymer

Proteins are composed of what smaller subunits?

• amino acids
• nucleic acids
• fatty acids
• nucleotides

Starch is composed of what monomers?

• sucrose
• glucose
• nucleic acids
• glycogen

Amino acids are so called because they:

• contain the NH2 group

• contain the COOH group

• turn blue litmus red

• contain the NH2 group and the COOH group

Which of the following is not an addition polymer?

• polystyrene

• terylene

• polyethene

• polypropene

Identify the type of polymer involved
