Hello friends and welcome to MOOC in Enzymology.
Enzymology is a specialized branch of life sciences that deals with the biochemical nature  and activity of enzymes and  is a subject that has relevance to students from a wide range of disciplines. In addition, it will serve as an individual reference for students pursuing their undergraduate/ post graduate degree programmes in life sciences and it could be recommended to anyone wishing to get an idea of the present day scope and applications of enzymology. The present course opens the door to all of the abundant careers in and out of the area of biological sciences including health/ medical / Environmental Sciences. The course is designed to give students an understanding of procedures involved in purification of enzymes, enzymes assays and quantitative evaluation of the influencing parameters such as concentrations of substrate / enzyme, pH, temperature and effects of inhibitors on enzyme activity.
This is a course where the topics to be studied include enzyme active sites / mechanisms of enzyme action; enzyme kinetics and regulation; collision and transition state theories;  Isozymes and their clinical significances /protein folding / site-directed mutagenesis  and molecular structure/ function relationship etc as tools for understanding functions of enzymes. This course is rich in pedagogical features like short answer type questions / self explanatory illustrations, MCQs etc. which help students to evaluate themselves and improve upon.
This course is fundamental to the acquisition of competencies to solve problems which impact daily life e.g., health and environment and also  students should acquire skills to initiate a research or industrial career (food, pharmaceutics or biotechnology) in the country or abroad. The main goal of this course is to prepare students for critical analysis of scientific phenomena involving enzymes and competently work with enzyme systems in both academia and industry.
Hence, the programme is designed to provide students with the knowledge and skills they need to explore the central questions in basic and applied biology.
Hope that the students belonging to all the fields of life sciences may take this as a course of study in their undergraduate and post graduate programs. All the best---
