D5 - How it’s made: Cholesterol production in your body Flashcards
What is the consequence of excess cholesterol in the bloodstream?
Excess cholesterol in the bloodstream is a key contributor to artery-clogging plaque
Besides contributing to artery plaque
what other functions does cholesterol serve in the body?
What percentage of cholesterol needed for a healthy body is produced by the liver?
About 80% of the cholesterol needed to stay healthy is produced by the liver; the remaining 20% comes from food.
How does the intestine contribute to cholesterol processing?
The intestine breaks down food
How does cholesterol travel through the bloodstream
considering it is a fat?
What are the five main types of low-density lipoproteins (LDL)?
Chylomicrons
What do chylomicrons mainly carry
and where are they made?
What do very-low-density lipoprotein (VLDL) particles carry
and what transformation occurs as the body extracts fatty acids from them?
What happens to intermediate-density lipoprotein (IDL) particles
and how do they contribute to low-density lipoproteins (LDL)?
Why is low-density lipoprotein (LDL) known as ‘bad’ cholesterol?
LDL is known as ‘bad’ cholesterol because it delivers cholesterol to tissues and is strongly associated with the buildup of artery-clogging plaque.
Why are high-density lipoproteins (HDL) considered ‘good’ cholesterol?
HDL is considered ‘good’ cholesterol because it removes cholesterol from circulation and artery walls
What are the resulting particles when chylomicrons and VLDLs interact with blood vessels or fatty tissue?
The resulting particles are remnant particles (if from chylomicrons) or IDLs (if from VLDLs)
