Study Notes
Introduction to Chemistry for Macromolecules
- The session references include Marks’ Basic Medical Biochemistry, Medical Biochemistry, Lippincott’s Illustrated Reviews: Biochemistry, and Lippincott’s Illustrated Reviews: Cell and Molecular Biology.
- The learning outcomes for the session include discussing important bonds for macromolecular structure and interaction, explaining the differences between hydrophobic and hydrophilic molecules in water, and understanding pH, pK, and buffers.
- The glossary includes definitions for terms such as acid, amino acid, amphipathic, base, buffer, covalent bond, hydrogen bond, hydrophilic, hydrophobic, ionic bond, isoelectric point, peptide bond, pH, and protein.
- Macromolecules are composed of subunits, which are held together by various bonds including covalent, ionic, hydrophobic, van der Waals, and hydrogen bonds.
- Water is important for weak interactions between biomolecules, and its properties include being a polar molecule and highly cohesive due to hydrogen bonding.
- Water is the principal fluid medium of the cell, and helps regulate temperature, intracellular pH, and is used for transport.
- Substances can be classified as hydrophilic, hydrophobic, or amphipathic based on their ability to dissolve in water.
- The ionization of water produces hydronium and hydroxyl ions, and the ion product of water is K w, which is 1.0 × 10-14 at 25°C.
- pH is a measure of the concentration of H+ in a solution, and pK is the pH at which an acid is half dissociated.
- Acid-base conjugate pairs act as buffers and resist changes in pH of a solution.
- The Henderson equation can be used to calculate pH, molar proportion of A- to HA, and pKa values.
- Understanding chemistry is crucial for understanding the structure and function of macromolecules in biological systems.
