Lehninger Principles of Biochemistry

Biochemical processes are presented as an integrated system, linking molecular structure with cellular function and metabolism. It explores proteins, nucleic acids, lipids, and carbohydrates while explaining how energy is generated, stored, and utilized through pathways such as glycolysis, the citric acid cycle, and oxidative phosphorylation. The text also connects gene expression, regulation, and signaling to broader physiological functions, emphasizing how molecular mechanisms sustain life and adapt to changing conditions.
