Acid-labile sulfur

{
  "id": "MLC-T-CHM-000142",
  "term": "Acid-labile sulfur",
  "field": "Chemistry",
  "definition": "Sulfur atoms in biological molecules that are readily released as hydrogen sulfide (H2S) upon treatment with a strong acid. This type of sulfur is typically found in iron-sulfur clusters within proteins, where it bridges iron atoms. The release of H2S is a common method for quantifying these specific sulfur atoms in metalloproteins.",
