Unformatted text preview: Chem114A Monday, September 26, 2011 What is Biochemistry? It is the study of the chemical basis of life Monday, September 26, 2011 What do biochemists aim for? To describe in molecular terms the structures, mechanisms and chemical processes shared by all organisms, providing organizing principles that underlie life in all its diverse forms. Monday, September 26, 2011 What questions does Biochemistry attempt to address? What is the chemical structure of living organisms? How do the basic components organize in complex structures like macromolecules, cells, tissues and organisms? How do organisms extract energy from their surroundings to remain alive? How are chemical reactions controlled inside the cells? How is information transmitted when organisms reproduce? Monday, September 26, 2011 Areas of Biochemistry Structural Biochemistry (what are the components of cells and how do these macromolecules work?) Chem114A Metabolism (what are the chemical reactions occurring in organims?) Chem114B Molecular genetics (how biological information is stored and transmitted?) Chem114C Monday, September 26, 2011 Areas of Biochemistry Structural Biochemistry (what are the components of cells and how do these macromolecules work?) Chem114A Metabolism (what are the chemical reactions occurring in organims?) Chem114B Molecular genetics (how biological information is stored and transmitted?) Chem114C Monday, September 26, 2011 How inanimate matter results in life? Isolated biomolecules conform to all the laws of chemistry and physics. How the unique properties of living organisms can be explained based on chemical and physical principles? Monday, September 26, 2011 Properties of living organisms High degree of chemical complexity and microscopic organization Systems to extract, transform and use energy from the environment Self-replication and self-assembly Sensing and responding to changes in environment DeFne function for each component and regulation among them History of evolutionary change Monday, September 26, 2011 Biochemistry is an interdisciplinary science Biology Chemistry Physics Monday, September 26, 2011 Foundations of Biochemistry...
