Blood lipid metabolism pathways

"Blood lipid metabolism pathways" refers collectively to the complex network of biochemical processes responsible for the digestion, absorption, transport, storage, and utilization of lipids in the body. These processes involve multiple types of molecules—including triglycerides, phospholipids, sterols like cholesterol—and specialized transport particles called lipoproteins such as chylomicrons, VLDL (very-low-density lipoprotein), LDL (low-density), IDL (intermediate-density), and HDL (high-density). The liver plays a central role in synthesizing endogenous triglycerides and cholesterols which are then distributed throughout the body via these particles. Enzymes such as lipases facilitate breakdown and mobilization; nuclear receptors regulate gene expression involved in fatty acid oxidation or synthesis; cell surface receptors mediate uptake from circulation into tissues. Dysregulation at any point can contribute to diseases like atherosclerosis or metabolic syndrome[1][2][3]. Note: "Blood lipid metabolism pathways" is not itself a discrete molecular target but rather an umbrella term describing interconnected physiological routes involving many distinct targets—enzymes like HMG-CoA reductase; transporters like NPC1L1; proteins such as apolipoprotein B100—each potentially serving as individual therapeutic targets depending on context. Therefore this entry is considered incorrect as a canonical drug target name under standard conventions.

Mechanisms depend on the specific molecular target within the pathway. For example, inhibition of cholesterol biosynthesis enzymes to lower plasma cholesterol levels; activation of nuclear receptors to increase fatty acid oxidation or decrease triglyceride synthesis; inhibition of intestinal absorption of dietary cholesterol.
