This article throws light upon the six factors affecting the enzyme activity. The six factors are: (1) Concentration of Enzyme (2) Concentration of Substrate (3) Effect of Temperature (4) Effect of pH (5) Effect of Product Concentration and (6) Effect of Activators. The contact between the enzyme and substrate is the most essential pre-requisite for enzyme activity. The important factors [...]
Read this article to learn about the use of enzymes in the diagnosis of diseases. Estimation of enzyme activities in biological fluids (particularly plasma/serum) is of great clinical importance. Enzymes in the circulation are divided into two groups: 1. Plasma specific or plasma functional enzymes: Certain enzymes are normally present in the plasma and they have specific functions to perform. [...]
Read this article to learn about the features, principle and types of biosensors. A biosensor is an analytical device containing an immobilized biological material (enzyme, antibody, nucleic acid, hormone, organelle or whole cell) which can specifically interact with an analyte and produce physical, chemical or electrical signals that can be measured. An analyte is a compound (e.g. glucose, urea, drug, [...]
