Cholesterol uptake, animation

Référence de la vidéo 11936423
Cholesterol uptake into the liver, animation. Cholesterol is an essential component of all cell membranes. It is insoluble in water, so it cannot be transported by the blood. Cholesterol is instead transported inside droplets called low-density lipoprotein (LDL) vesicles (detail, left). LDL receptors on the surface of liver cells recognise these vesicles and ingest them by infolding the cell membrane, a process called endocytosis. LDL receptors are returned to the surface, and the LDL vesicles are broken down by lysosomes (pouch of digestive enzymes, coming from right). Cholesterol is released into the cell to be used in various processes. For an unlabelled version of this animation, see K004/0953.
