Weak acids & bases, pka, and the henderson hasselbalch equation\ Define biochemistry and its role in living organisms. Outline the material to be covered in this course. The four major classes of biomolecules (carbohydrates, lipids, proteins, & nucleic acid) First law of thermodynamics & enthalpy (h) Second law of thermodynamics & entropy (s) aka randomness. [h+], ph and the role of ph on biological systems. Weak acids & bases, pka, and the henderson hasselbalch equation. Structure: amino, carboxyl, c , and r groups: ionization. Grouping the 20 amino acids ( : non-polar & aliphatic amino acids, aromatic amino acids, basic (positively charged) amino acids, acid (negatively charged) amino acids, polar amino acids. Polypeptides are flexible but conformationally restrained : double bond characteristics of the peptide bond, dihedral angles: (phi) and (psi) Polypeptides are flexible but conformationally restrained : dihedral angles: (phi) and (psi) Sheets: structure and properties: parallel, antiparallel, and mixed. Definition and properties: example: hemoglobin & mvm.
