Definition of Biochemistry “Chemistry of Life” Living Things are composed of lifeless molecules Doesn’t fully take in<strong>to</strong> account what chemistry is Biochemistry- Study of the structure, properties and changes of bio-matter
Special Considerations 1. Complex and highly ordered 2. Everything has a function 3. Living things transform their environment (extract energy) 4. Self-replicating 5. Reactions occur at constant temperature, pressure and pH; in an aqueous environment
