Flashcards in Unit 2- Molecules of life Deck (7)
What makes up all living things?
C has 4 outer (vaillent) electrons (6p, 6n) making it really good a bonding so it can make fairly stable large carbon molecules.
What is a functional group?
Name 6 functional groups.
What is its structure?
What do they do?
Parts of a molecule that give it behaviour.
What are monomers?
What are polymers?
Monomers - The building blocks of Polymers
Polymers - Large macromolecules
How are polymers made?
What are the products of this reaction?
Dehydration reactions - Amino Acids bond together. in this process a [OH] from its carboxyl functional group bonds with a [H] from its amino functional group. This results in water as a byproduct.
Water & a Polymer with a peptide bond where the water has been taken from.
How are Polymer broken down?
Hydrolysis - Water is added to a polymer. This causes the peptide bond to break.
What are 4 Polymers?
What are its monomers?
Nucleic Acids (e.g RNA DNA) - made from nucleotides.
Proteins - made from amino acids.
Lipids - fatty acids and glycerols
Carbohydrates ( disaccharides and polysaccharides ) - monosaccharides.
