Biomolecules: Structure Function in Health and Disease

All India Institute of Medical Sciences, New Delhi and CEC via Swayam


This course on Biomolecules is one of the basic course for all PG Students of Biological Sciences. This is 4 credit course. Gives an overview of importance of biomolecules starting from the simplese molecule, water. Elaborate the need to study proteins: Their 3D Structure,protein seperation,sequencing etc. To understand the pathology and identifying biomrakers using clinical proteomics. Explain in detail DNA,RNA their structures, interactions role in disease,genomics.epigenetics. Enumerate the role of carbohydrates,lipids and their cellular function in physiology and pathology. To briefly introduce to system biology
