  1. What is a free fatty acid called?
    unesterified
  2. What is the structure of a fatty acid?
    hydrophobic hydrocarbon chain with terminal carboxyl group
  3. What type of fatty acid has no double bonds?
    saturated
  4. Are fatty acids with double bonds usually cis or trans?
    Cis
  5. how many carbons are between each double bond?
    3
  6. what is the number given to the carboxyl carbon, alpha carbon, beta carbon?
    • 1
    • 2
    • 3
  7. What are the two essential fatty acids?
    • Linoleic acid
    • Alpha-Linolenic acid
  8. what becomes essential if linoleic acid is deficient?
    arachidonic acid
  9. What is needed for acetyl CoA to cross the mitochondrial membrane into the cytoplasm?
    • Acetyl and OAA cross via Citrate (citrate synthase)
    • CoA is able to cross on own

    16
  14. how many steps how many times to make palmitate?
    7 steps repeated 5 times
  15. What enzyme is used to attach fatty acids to glycerol back bone?
    acyltransferase
  16. what is needs to be removed before the last fatty acid is added?
    phosphate
  17. What is the glycerol backbone?
    glycerol-3-phosphate
  18. What enzyme converts DHAP to glycerol-3-phosphate?
    Glycerol-3-phosphate dehydrogenase
  19. what enzyme is used to conver glycerol in the liver and kidney to glycerol-3-phosphate?
    glycerol kinase
  20. What converts FA to activeated form?
