Biochemistry: Ka, pKa & Dissociation Constants

The Chemical Compass of Life (Biochemistry Notes)

Master the constants that govern acid-base chemistry and biological control.

📂 Topics Covered:

• The Dissociation Constant (Ka): Measuring acid strength and proton donation tendency.
• The pKa Scale: Why a lower pKa means a stronger acid (The Logarithmic Rule).
• Henderson-Hasselbalch Equation: Predicting ionization states and the ratio of proton donor to acceptor.
• Biological Buffers: How systems resist pH changes (Effective range = pKa ± 1).
• Titration Curves: Finding the midpoint where pH = pKa.
• Protein-Ligand Binding: Understanding Kd vs Ka in a biological context.

✅ Perfect for: NEET/CSIR-NET aspirants needing to master the math of acid-base balance and enzyme kinetics.
