- VLDL: 10 - 15%
5
Q
- In what organ is cholesterol made in?
- How many steps involved in production?
- Made from what?
A
- Liver
- 25
- Acetyl CoA (breadown product of FFA)
6
Q
Is cholesterol synthesized by the liver during morning or night time?
A
Predominantly at night
7
Q
What substance is associated w/ the rate limiting step in synthesis of cholesterol by the liver?
A
HMG-CoA reductase
8
Q
- HMG-CoA reductase converts HMG-CoA to ____ during the rate limiting step.
- What is controlled during this step?
A
- mevalonate
- Negative feedback is controlled (high levels of LDL)
9
Q
- What type of drug is an HMG-CoA reductase?
- What can happen if dosage is too high?
A
Statin. * IF we lower cholesterol too much, if can affect our sex hormones.

- Appropriate intensity of statin to reduce ASCVD
14
