24. Classification of Lipids. Digestion and Absorption of Lipids. Synthesis of Chylomicrons.
Covers the classification of lipids into simple, complex and derived groups, with examples of each. It then walks through digestion in the stomach and small intestine, emulsification by bile salts, the enzymes involved and micelle formation, followed by absorption into enterocytes and re-esterification. It ends with chylomicron synthesis, their route via lacteals and the thoracic duct, and their processing in the blood and liver.

Classification of Lipids
Lipids are hydrophobic or amphipathic biological molecules.
They serve as energy sources, structural membrane components, and signaling molecules.
Main classes:
a) Simple Lipids
Fats (Triglycerides): glycerol + 3 fatty acids → main energy storage form.
