Introduction of biochemistry

Biochemistry
Biochemistry has become the foundation for understanding all biological
processes.
It has provided explanations for the causes of many diseases in humans,
animals and plants
What is Biochemistry
 Biochemistry is the application of chemistry to the study of biological processes at the cellular and molecular level.
It emerged as a distinct discipline around the beginning of the 20 th century when scientists combined chemistry, physiology and biology to investigate the chemistry of living systems by:
A.Studying the structure and behavior of the complex molecules found in biological material and
B.the ways these molecules interact to form cells, tissues and whole organism
Principles of Biochemistry
Cells (basic structural units of living organisms) are highly organized and constant source of energy is required to maintain the ordered state.
Living processes contain thousands of chemical pathways. Precise regulation and integration of these pathways are required to maintain life
Certain important pathways e.g. Glycolysis is found in almost all organisms.
All organisms use the same type of molecules: carbohydrates, proteins, lipids & nucleic acids.
Instructions for growth, reproduction and developments for each organism is encoded  in their DNA
