  "id": "MLC-T-CHM-007298",
  "term": "Michaelis constant",
  "field": "Chemistry",
  "definition": "A measure of the substrate concentration at which an enzyme reaction rate is half of its maximum velocity (Vmax). It reflects the affinity of an enzyme for its substrate, with a lower value indicating higher affinity. This constant is a fundamental parameter in Michaelis-Menten kinetics, describing enzyme-catalyzed reactions.",
