Enzyme analysis refers to the process of measuring the activity, quantity, specificity, and/or structural properties of enzymes in biological, clinical, or industrial samples. It involves a range of biochemical, biophysical, and molecular tools, such as spectrophotometry, electrophoresis, chromatography, mass spectrometry, and gene cloning/sequencing. Enzyme analysis is important in various fields, such as medicine, biotechnology, food science, and environmental science, for understanding enzyme function, regulation, and dysfunction, and for developing diagnostic, therapeutic, and biocatalytic applications. It requires expertise and training in enzymology, biochemistry, and analytical techniques.
