ACS BIOCHEMISTRY EXAM QUESTION WITH COMPLETE SOLUTIONS LATEST 2024. Henderson-Hasselbach Equation - CORRECT ANSWER - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - CORRECT ANSWER - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the Nterminus. Salting Out (Purification) - CORRECT ANSWER - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution....
