How is cholesterol synthesized
WebThe HDL particle is synthesized mainly by the liver, and also by the intestines. When excess cholesterol occurs in extra-hepatic tissues, it is picked up by HDLs by a process called reverse cholesterol transport. Apo A-I is the vital and defining protein of the HDL. Each HDL particle contains 2–4 molecules of Apo A-I. Web24 okt. 2008 · Fat Finds Its Voice. Megan Talkington October 24, 2008. Our gut reaction to fat is that it’s bad.
