Lipid Metabolism — Flashcards

As surfactant production is increased (fetal lung maturation), _____ levels increase, while sphingomyelin levels remain constant

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

Increased levels of cholesterol inside the hepatocyte leads to _____ activity of the enzyme HMG-CoA reductase

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

_____ is characterized by a deficiency of apolipoprotein B-48 and B-100

Apoprotein _____ mediates chylomicron remnant uptake in the liver

Acetyl-CoA is converted to _____ via the enzyme HMG-CoA synthase (ketogenesis)

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
