The core task of this step is to select a representative biomedical chemistry problem and define the research scope and specific objectives. It requires combining chemical principles learned (equilibrium, thermodynamics, kinetics, acid-base balance, etc.) to select problems suitable for quantitative analysis and mechanistic explanation.

• Choose a specific problem from blood acid-base balance, enzyme catalysis kinetics, electrolyte balance, pharmacokinetics, osmotic pressure, protein denaturation, etc.; define research object and scientific question
• Define research scope: identify relevant chemical principles (Henderson-Hasselbalch equation, Michaelis-Menten equation, Nernst equation, etc.); specify quantitative parameters to be calculated
• Review relevant literature and textbooks; understand physiological significance and clinical application value; write a topic proposal explaining research significance and expected objectives

The core task of this step is to deeply analyze the underlying mechanisms of the selected biomedical problem using fundamental chemical principles, explaining physiological or pathological processes at the molecular level. It connects abstract chemical concepts with concrete biomedical phenomena.

• Systematically review relevant chemical principles: e.g., using Henderson-Hasselbalch equation for blood pH buffer mechanism in acid-base balance, transition state theory and Michaelis-Menten equation for enzyme catalysis
• Mechanism analysis: draw schematic diagrams of chemical processes (buffer pair mechanism, enzyme-substrate binding model, reaction coordinate diagram); label key intermediates and energy changes
• Analyze influencing factors: discuss effects of temperature, pH, concentration, inhibitors on chemical processes; connect to physiological/pathological states (acidosis, alkalosis, fever)

The core task of this step is to perform specific quantitative calculations, describing and predicting biomedical chemistry processes through mathematical models. It requires setting reasonable parameters and conditions, deriving formulas and numerical calculations to obtain quantitative results.

• Set calculation parameters: e.g., carbonate buffer concentrations in blood (normal physiological range), enzyme Km and Vmax values, substrate concentration ranges; cite parameter sources (literature or textbooks)
• Perform quantitative calculations: e.g., calculate blood pH at different CO2 partial pressures, reaction rates at different substrate concentrations, equilibrium constants and reaction direction, osmotic pressure and membrane potential; show complete calculation processes
• Plot relationship curves: use Excel or Python to plot pH-CO2 relationship curves, rate-substrate concentration curves, concentration-time curves to visually demonstrate quantitative relationships

The core task of this step is to review relevant literature to verify the reasonableness of theoretical analysis and calculation results, and apply analysis to actual clinical cases. Literature validation confirms correctness of analysis; case analysis demonstrates practical value.

• Literature search: use PubMed, CNKI and other databases to search for research papers and reviews; collect experimental data and clinical study results; retrieve at least 10 Chinese and English references
• Result comparison and validation: compare your calculation results and theoretical analysis with experimental data reported in literature; analyze consistency and differences; discuss possible reasons
• Clinical case analysis: select 1-2 relevant clinical cases (e.g., metabolic acidosis patients, organophosphate poisoning patients); use chemical principles to explain clinical manifestations and treatment mechanisms

The core task of this step is to write a complete research report systematically presenting background, principle analysis, quantitative calculations, literature validation, and clinical applications. The report should have clear structure, rigorous logic, and be well-illustrated.

• Write research report following academic standards: abstract (bilingual), introduction, chemical principles and mechanisms, quantitative calculations and results, literature validation and comparison, clinical application and discussion, conclusion, references; minimum 3000 words
• Create high-quality figures and tables: chemical structure diagrams, reaction coordinate diagrams, data curves, tables; clear figure/table captions; accurate data annotations; proper citation format
• Summary and outlook: summarize main findings, analyze study limitations, outlook future research directions and application prospects in this field
