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.

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

Diagram showing common functional groups in monomers-amine, carboxylic acid, alcohol, and isocyanate-at the top, and their resulting polymer linkages-amide, ester, and carbamate (urethane)-at the bottom, with color-coded chemical structures and connecting lines illustrating how monomers combine during polymerization.

Diagram showing the hydrolysis of an ester, where methyl acetate reacts with water to produce acetic acid and methanol, with molecular structures and chemical formulas illustrated.
