  "id": "MLC-T-CHM-007242",
  "term": "Metabolism quenching",
  "field": "Chemistry",
  "definition": "The rapid cessation of all metabolic activity within a biological sample, performed immediately after collection to preserve the metabolic profile. This process prevents post-sampling changes in metabolite concentrations due to enzymatic reactions or degradation. Common methods include rapid cooling to cryogenic temperatures or the addition of strong acids or organic solvents.",
