BioChem Eicosanoids

LECOM Biochem Eicosanoids Ch 35

QuestionAnswer
Cyclo-oxegenase pathway leads to creation of prostaglandins and thromboxanes
Lipoxegenase pathway leads to creation of leukotrienes, HETEs and lipoxins
Cytochrome P450 pathway leads to creation of epoxides, HETEs and diHETEs
First 3 precursors in the COX system AA->PGG2->PGH2
Prostacyclin Abreviation? Where created? PGI2 and vascular endothelium
Prostaglandins all vasodilatem increase cAMP, and decrease: platelet and leuk agg., IL-1/2 except? PGF2a
PGF2a causes vasoconstriction, bronchoconstriction, smooth muscle contraction
TXA3 causes less______ than TXA2 platelet aggregation
3 carbons lipoxygenases act on 5, 12 and 15
5- 12- and 15- lipoxygenase specific cells 5- PMN leuks, 12- platelets, 15- eosinophils
LTB4 causes increase in vascular permeability, T-cell prolif, Leuk agg, INF-γ, IL-1/2
LTC4 and LTD4 can increased bronchoconstriction, vascular permeability, and IFN-γ
These levels, measured in urine, correlate to levels of oxidative stress Isoprostanes
3 neuro diseases that cause increased oxidative stress Alzheimers, Parkinsons, ALS
These activate cAMP-protein kinase A system PGD, PGE, PGI
These increase intracellular calcium PGF2a, TXA2, endoperoxides, and leukotrienes

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
