Cholesterol - Wikipedia
Physiology. Cholesterol is essential for all animal life. While most cells are capable of synthesizing it, the majority of cholesterol is ingested or synthesized by hepatocytes and transported in the blood to peripheral cells. The levels of cholesterol in peripheral tissues is dictated by a balance of uptake and export. [11] .

Biochemistry, LDL Cholesterol - StatPearls - NCBI Bookshelf
2023年8月8日 · LDL cholesterol, or low-density lipoprotein cholesterol, is a fat that circulates in the blood, moving cholesterol around the body to where it is needed for cell repair and depositing it inside of artery walls. Because cholesterol and triglycerides are insoluble in water, they must be associated with proteins to flow through the hydrophilic blood.
