Funkcija

uredi

Hranjive masti se crijevima pakiraju u trigliceridima bogate lipoproteina zvane hilomikroni. Trigliceridi u hilomikronima se hidroliziraju lipoprotein-lipazom (LPL) duž lumenake površine kapilara, uglavnom u srcu, skeletnim mišićima i masnom tkivu. GPIHBP1 je protein kapilarnih endotelnih ćelija koji pruža platformu za LPL-posredovanu obradu hilomikrona.[5][7]
