Structural formula diagram of a tristearin molecule showing a central glycerol backbone highlighted in pink, with three long stearic acid fatty acid chains branching downward, each composed of repeating CH2 units. A detailed cross-section illustration of a low-density lipoprotein (LDL) complex shows a spherical structure with a phospholipid monolayer, embedded apoprotein (apoB-100), and internal components such as cholesteryl esters, free cholesterol, and triacylglycerol molecules. Diagram showing how fatty acids are mobilized from adipose tissue, transported in the bloodstream, processed in the liver, and delivered as energy sources such as fatty acids, triglycerides, and ketones to the muscle, brain, and heart. Arrows illustrate the movement and conversion of lipids, glucose, glycerol, and ketones between adipocytes, liver, muscle, heart, and brain. Detailed diagram showing the transport of lipoproteins in the human body, illustrating how dietary fats and cholesterol are absorbed in the small intestine, packaged into chylomicrons, and transported through lymphatic vessels and the bloodstream. The diagram traces the conversion of chylomicrons to VLDL, IDL, LDL, and HDL particles, highlighting their roles in fat and cholesterol delivery, storage, and recycling, with labeled pathways to the liver, muscle, and adipose tissue, and includes cellu
