High density lipoproteins transport

High-density lipoprotein (HDL) is one of the five major groups of lipoproteins. Lipoproteins are complex particles composed of multiple proteins which transport all fat molecules (lipids) around the body within the water outside cells. They are typically composed of 80–100 proteins per particle (organized by one, two or three ApoA. HDL particles enlarge while circulating in the blood, aggregating more fat molecules) and transporting up to hundreds of fat molecules per particle. WebValentin Blanchard, Gordon A. Francis, in Biochemistry of Lipids, Lipoproteins and Membranes (Seventh Edition), 2024. Abstract. High-density lipoproteins (HDLs) are lipid–protein complexes that mediate the transport of cholesterol from non-hepatic tissues to the liver for excretion from the body, a process known as reverse cholesterol …
