 Of the fatty acids contributing to Caucasian men's underarm odor, TMHA has the most prominent odor.It has long been claimed that schizophrenia patients exhibit a particular peculiar body odor, and it has been postulated the odor may be caused by underlying metabolic abnormalities associated with the condition, among other factors.Initial studies identified the causal component as TMHA, however, subsequent studies failed to reproduce such results, with subsequent researchers suggesting the initial research may have had misidentified impurities in samples as TMHA due to poor methodology.
