The flashcards below were created by user jennyroyter on FreezingBlue Flashcards. What would you like to do?


  1. methyl group is the only one that is
    nonpolar and not ionized
  2. hydrocarbon
    molecule with only C and H atoms
  3. asymmetrical carbon
    • left + right isomers
    • enantiomers
  4. carbohydrates
    • very water solubile
    • a variation of CH2O
    • energy storage-plants store it as sugar
    • "starch" is amylose ex. grains, root crops, tapioca
    • monosaccharides ex. triose (3 carbons), pentose (5 carbonds), hexoses (6 carbons)
    • disaccharides.
    • e.g. sucrose (glucose and fructose)
    • maltose (glucose and glucose)
    • lactose (glucose and galactose)
  5. Name large biological molecule, monomer, and linkage for carbohydrate.
    • polysaccharides
    • monosaccharides
    • glycosidic linkage
  6. Name large biological molecule, monomer, and linkage for protein
    • protein/polypeptide
    • amino acid
    • peptide bond
  7. Name large biological molecule, monomer, and linkage for lipids (any substance that is hydrophobic)
    • triglyceride *only one that's not a polymer*
    • 1 glycerol+3 fatty acids
    • ester linkage
  8. Name large biological molecule, monomer, and linkage for nucleic acid
    • DNA+RNA
    • nucleotides
    • phosphodiester
  9. by what method are all polymers made and broken up
    dehydration synthesis and hydrolysis
  10. dehydration synthesis/condensation reaction
    forms bonds by removing a water molecule
  11. hydrolysis
    • breaks down macromolecules by the addition of a water molecule
    • it happens only with the help of enzymes
  12. polysaccharides
    • energy storage
    • structural
    • amylose=starch
    • glycogen=animal starch
    • cellulose=structural for cell walls of plants
    • chitin=cell wall of fungi/exoskeleton
  13. alpha glucose
    • hydroxyl group is down
    • amylose=a polymer of alpha 1,4 glycosidic linkages
    • easy to digest
  14. beta glucose
    • hydroxyl group is up
    • not digestable e.g. fabric, wood
    • celloluse beta 1,4 glycosidic linkage
  15. lipids
    • anything that is hydrophobic
    • ex. hydrocarbonds, fatty acids, steroids, cholesterol, testesterone, triglyceorides
    • wax
  16. triglyceride is
    fat. by law.
  17. saturated fat
    • triglyceride that is solid at room temp
    • e.g. butter, margarin, lard
  18. unsaturated fat
    • triglyceride that is liquid at room temp
    • e.g. olive oil, soy bean oil, walnut oil, almond oil, peanut oil
    • has at least 1 double bond which makes a kink in the molecule
  19. saturated and unsaturated structure
