  1. Ketone bodies made from carbon skeleton from AA metabolism?
    Acetone, Acetoacetate, Beta-hydroxy butyrate
  2. Difference between Hartnup/Cystinuria and Marasmus/Kwashiorkor?
    Hartnup/Cystinuria = no protein malabsorption

    Marasmus/Kwashiorkor = protein malabsorption
  3. Kwashikor 
    protein contents in diet?
    no, characterized by decrease in protein consumption (similar to Marasmus)
  4. Kwashikor 
    Caloric intake?
    normal
  5. Kwashikor 
    suffer from fatty liver & subcutaneous fat?
    yes and yes
  6. Kwashikor 
    pellagra like symptoms?
    Yes (bc protein malabosortpion so Trp can't make niacin, therefore niacin deficiency)
  7. Kwashikor 
    plasma level of free A.A.?
    No (bc caloric intake is fine)
  8. Kwashikor 
    Hypoalbuminemia and edema?
    Yes and yes (remember that they're fat so edema and low albumin serum levels)
  9. Marasmus
    protein content in diet?
    low
  10. Marasmus
    caloric intake?
    low
  11. Marasmus
    suffer from fatty liver?
    no
  12. Marasmus
    subcutaneous fat?
    no
  13. Marasmus
    pellagra?
    Yes
  14. Marasmus
    plasma level of free A.A.?
    normal (bc skeletal muscle is broken down to make AA in blood)
  15. Marasmus
    Hypoalbuminemia and edema?
    No and no
  16. Glucogenic AA's?
    • PAFSO (P = CThreeSWAG, A = GHArPG, F = FAsT, S = Il(ove)MTV, O = Aspartate, Asparagine)
    • P = pyruvate; A = Alpha-Keto Gluterate, F = Fumerate, S= Succinyl CoA, O = Oxaloacetate)
  17. Ketogenic AA's (i.e. give rise to Acetyl CoA)?
    Leucine and Lysine
  18. Both Keto- and Glucogenic?
    FIsY-Tryp = (W,Phe,Isoleucine,Tyrosine)
