HDL: high-density (removes cholesterol from blood) lipoprotein: "bad cholesterol" 
lipoprotein: group of soluble proteins that transports lipids in blood plasma 
*** Neither one is actually good or bad because you need a balance between LDL and HDL in your body]]> 2018-03-18 21:58:17 UTC https://padlet.com/s1000261655/cholesterol333/wish/243262422 Functions of LDL and HDL s1000261655 https://padlet.com/s1000261655/cholesterol333/wish/243270284 LDL: transports cholesterol to cells to produce protective walls around them 
- liver or macrophages (scavenger cells )remove remaining LDL 
- too much LDL -> binds to artery walls  -> clogs arteries -> leads to cardiovascular disease 
HDL: binds excess cholesterol transferring it to other lipoproteins or the liver for removal through the intestines

- 50% cholesterol 
- 25% protein 
- less dense than LDL 
- twice the size HDL
- contains B-100 proteins (form of LDL that moves cholesterol around the body) 
- richest in cholesterol than all the other lipoproteins 

HDL:
- 20% cholesterol 
- 50% protein 
 - more dense structures than LDL because protein is more dense than fat 
- contains A-I and A-II proteins (apoproteins of HDL) ]]> 2018-03-18 23:28:51 UTC https://padlet.com/s1000261655/cholesterol333/wish/243274944 s1000261655 https://padlet.com/s1000261655/cholesterol333/wish/243276353 2018-03-18 23:38:46 UTC https://padlet.com/s1000261655/cholesterol333/wish/243276353 March 16, 2018.
