L-Lactate dehydrogenase (LDH) is an enzyme that plays a crucial role in the metabolic process of converting pyruvate to lactate during anaerobic respiration, as well as the reverse reaction under aerobic conditions. It is a tetrameric enzyme composed of four subunits, which can be combinations of two types of subunits, M (muscle) and H (heart), leading to different isoforms with varying kinetic properties and tissue distributions. LDH is widely distributed in various tissues, including the heart, liver, and skeletal muscle, and is essential for maintaining the balance of NAD+/NADH in cells. The enzyme is often used as a biomarker in clinical diagnostics, particularly in assessing tissue damage or disease states, such as myocardial infarction or liver disease, as elevated levels of LDH can indicate cellular injury. LDH operates optimally at physiological pH and temperature, and its activity can be influenced by factors such as substrate concentration, pH, and the presence of inhibitors or activators.
