Flashcards
polymers
Cards in this deck (16)
- 1condensation polymerscan be made by joining dicarboxylic acids monomers and diol monomers
- 2what are the monomers joined together byEster links
- 3what is a dimertwo monomers combined
- 4when is a polymer referred to as condensation polymerwhen water is produced as a by product of the reaction
- 5Biodegradablebreak down naturally
(bacteria can break down ester links)
E.G condensation polymers- ester links can be broken down by microorganisms - 6plastics aren't biodegradablethey can't be broken down so they stay in the environment for ages
- 7each time ester link is formedmolecule of water is lost
- 8polmerslong chain of small molecules called monomers
- 9what do amino acid monomers combine to formpolypeptide
(form amino acids once they fold up) - 10what functional group does an amino acid havean R group
carboxylic group
amino group - 11what reaction takes place when an amino acid combines to form a polypeptidecondensation reaction
- 12bond formed in condensation reaction between two amino acidsamide bond
amide link
peptide bond - 13what monomers combine to form DNAnucleotides
- 14DNA Moleculesconsist of two polymer chain that coil around each other in a double helix- helps protect DNA from damage
- 153 elements that make up carbohydratesoxygen
carbon
hydrogen
carbohydrates polymers - starch , cellulose, glycogen - 16—
