Enzymes are pivotal part of living system. They are biological catalysts that perform myriads of metabolic reactions that sustain life. Enzymes facilitate life process in all life forms ranging from prokaryotes to eukaryotes. Hence the study of enzymes is crucial in understanding biochemical basis of life.This course on ‘Basic concepts in Enzymology’ is designed to introduce students to various theoretical and practical aspects of enzymology. This course will cover topics such as Enzyme classification and nomenclature, mechanism of enzyme action and the factors affecting their activities, enzyme kinetics, enzyme inhibition, regulation of enzyme activity, isolation and purification of enzymes and various industrial and clinical applications of enzymes. The course will consist of lectures, tutorials and interaction/discussion sections. This is an introductory course intended for undergraduate students in Biochemistry, Biotechnology, Microbiology and other life science courses including Botany, Zoology etc. Basic understanding about the biological catalysts can open new avenues for interdisciplinary research. Further, this course would serve as foundation for advanced Enzymology studies.
