Biochemistry is about the conversion of energy and the flow of information.

'''The Four Pillars of Life''':
1. '''Proteins (The Machines)''': Their function is determined entirely by their 3D shape. If a protein "unfolds" (denatures), it stops working.
2. '''Carbohydrates (The Fuel)''': Glucose is the "gasoline" of life. It is burned in mitochondria to produce ATP.
3. '''Lipids (The Walls)''': Cell membranes are made of a "lipid bilayer." One side likes water, the other hates it, creating a perfect waterproof seal for the cell.
4. '''Nucleic Acids (The Code)''': DNA stores the sequence; RNA carries it to the protein factories.

'''Metabolic Pathways''': Chemical reactions in the body don't happen in isolation; they happen in "assembly lines." For example, '''Glycolysis''' is a 10-step process that turns one molecule of glucose into energy. Each step is controlled by a specific enzyme. If even one enzyme is missing (due to a genetic mutation), the whole system can fail, leading to metabolic diseases.

'''Enzyme Specificity''': Enzymes are "Lock and Key" mechanisms. They only work with specific substrates. This prevents the body from accidentally breaking down the wrong molecules.
