Lead Sulfide Test- Definition, Principle, Procedure

2020-11-23  Lead sulfide test (or Lead acetate test) is a biochemical test for the detection of amino acids like cysteine and cystine. The test is a specific test for the detection of amino acids containing sulfur, S-S group in cysteine, and S-H group in cystine. The test is also called a lead acetate test as the reagent for the test is lead acetate.

Lead acetate test (Lead sulfide test): Principle,

2020-4-16  The sulfur-containing amino acid such as cysteine, cysteine, and methionine (sulfhydryl/thiol group) reacts with lead acetate under alkaline conditions to form a brown precipitate. These sulfur-containing amino acids are degraded in strongly alkaline media to release sulfide ion (S 2-) in the form of H 2 S (hydrogen sulfide). The sulfide ions can react with lead (II) acetate to form a brownish-black
