**Biochemistry Calculator Suite** is a comprehensive, zero-dependency command-line utility engineered in pure ANSI C for researchers, students, and laboratory professionals. It unifies three specialized modules into a single executable: **General Chemistry** (periodic table lookup, molar mass parsing with recursive descent, ideal gas law, solution chemistry), **Bioinformatics & Sequence Analysis** (DNA/RNA/protein molecular weight, GC content, melting temperature via Nearest-Neighbor thermodynamics, reverse complement, translation, isoelectric point via iterative pH scanning), and **Advanced Biochemistry** (enzyme kinetics, buffer preparation via Henderson-Hasselbalch, Beer-Lambert law, radioactive decay, concentration conversions). Designed for offline, cross-platform use on Windows, Linux, and macOS, the suite requires only a standard C compiler and `libm`. Its modular architecture enables flexible compilation—interactive menu-driven or CLI argument-based workflows—while strict input validation, buffer-safe string handling, and explicit memory management ensure robustness. Key algorithms include SantaLucia (1998) dinucleotide parameters for Tm, Kyte-Doolittle hydropathy indices, and Henderson-Hasselbalch-based buffer mass calculations. With a compact binary footprint (~50 KB), sub-millisecond computation latency, and MIT licensing, the toolkit delivers accurate, reproducible results for academic, research, and educational applications. Whether calculating protein extinction coefficients, preparing phosphate buffers, or translating genetic sequences, Biochemistry Calculator Suite transforms complex biochemical formalisms into accessible, deterministic computations—empowering users with reliable, keyboard-driven scientific utility. 🔬🧪💻
