Welcome to the class of Principles of Biochemistry with Dr. Meera Kaur. Explore the scientific discipline that explains life at the molecular level, elucidating biological forms and functions in chemical terms. Biochemistry serves as the foundation for studying fields like cell biology, genetics, medicine, nutrition, and immunology. Discover the levels of organization in living organisms, biomolecules, and elements in biological molecules. From major biomolecules like carbohydrates, proteins, lipids, and nucleic acids to the distinctions between Prokaryotes and Eukaryotes, delve into the structure of life itself. Learn about the laboratory synthesis of biological molecules, cyanobacteria, evolutionary processes, and more. Join us to unravel the secrets of biochemistry!

Welcome to class of Principles of Biochemistry Dr. Meera Kaur
What is Biochemistry? A scientific discipline Explains life at the molecular level Explains biological forms and functions in chemical terms Forms basis for studying other fields like cell biology, genetics, medicine, nutrition, immunology etc. Closely relates to other discipline like chemistry, physics, mathematics
What is biomolecule? What are living organism made of ? How are they made ?
Biomolecules Living matters are made out of biomolecules Biomolecules are made of lighter elements They are mostly combined with covalent bonding Biomolecules are compounds of carbon Biomolecules have functional groups Most biomolecules are asymmetric
What are the major biomolecules? Carbohydrates Protein Lipids Nucleic acds
Prokaryotes (bacteria, archae) Unicellular No nucleus Lack internal membrane systems Incapable of carring complex reactions Eukaryotes (animal, fungi) Multicellular/ unicellular Contain nucleus Have membrane-bounded cellular units Capable to perform cpmplex biological reactions (photosyntesis, aerobic metabolism etc.) Form of life
