Biochemistry

Skatol and indole are formed from tryptophan: Hydrogen sulfide (H 2 S), mercaptan (CH 3 SH) and other sulfur-containing compounds are formed with the intestinal microorganisms deeply destroying of sulfur-containing amino acids - cystine, cysteine and methionine. Products of rotting proteins are absorbed into the venous blood, then enter the liver, where they are neutralized with sulfuric or glucuronic acid. This process is carried out as follows: Phenol Sulfuric Acid Phenol Sulfuric Acid COOH COOH Phenol Glucuronic Acid Phenol Glucuronic Acid Indole and skatol are also neutralized in the liver with the participation of sulfuric and glucuronic acids. However, they are pre-oxidized: skatol to scatoxyl, indole to indoxyl and in the form of paired acids is excreted from the body in the urine. 162
