Lipid Metabolism — Flashcards

_____ increases testosterone synthesis by stimulating the enzyme cholesterol desmolase

Triglycerides in chylomicrons are hydrolyzed by the enzyme _____, releasing free fatty acids

In the blood, free radicals may take an electron from apoprotein _____ on LDL, forming oxidized LDL

The enzyme _____ may convert cholesterol to cholesterol ester in the blood in the presence of apoprotein A (found on HDL)

17-hydroxypregnenolone may be converted to _____ via the enzyme 17,20-lyase

Depletion of triglycerides from VLDLs produces _____, which may undergo further removal of triglycerides via the enzyme hepatic TG lipase, forming LDL

Apoprotein _____ mediates chylomicron remnant uptake in the liver

Once in the vicinity of the liver, the chylomicron remnant binds the _____ receptor via apoprotein E

In the ovaries, _____ cells synthesize and secrete progesterone from pregnenolone via the enzyme 3-hydroxysteroid dehydrogenase

Apoprotein _____ binds the LDL receptor on the liver
