Metabolite Identification
Common NameTuberculostearic acid
DescriptionTuberculostearic acid is the characteristic fatty acid of acid-fast bacteria of the order Actinomycetales. (PMID 3329256 ). Tuberculostearic acid (TBSA) is a mycobacterial cell wall constituent that is possible to measure in plasma samples of patients with active tuberculosis. (PMID 14723350 ). Detection of tuberculostearic acid in cerebrospinal fluid by use of gas chromatography-mass spectrometry has proven to be a very rapid, sensitive, and specific test for tuberculous meningitis. (PMID 8438134 ). Tuberculostearic acid can also be found in Actinomycetales (PMID: 109465 ).
