suur kompleks, mis koosneb ühest valgu molekulist ja paljudest estritega seotud kolesterooli molekulidest ning teistest lipiididest, Lipoproteins are complex particles composed of multiple proteins, typically 80-100 proteins/particle (organized by a single apolipoprotein B for LDL and the larger particles). A single LDL particle is typically transporting 3,000 to 6,000 fat molecules/particle. They are involved in the transport and intake of cholesterol.
