Metabolite Identification
Common Name3-hydroxy-3-methylhexanoic acid
Description3-hydroxy-3-methylhexanoic acid is a carboxylic acid metabolite that plays a role in human body odor composition. Its chemical structure features a hydroxyl group and a methyl branch on the hexanoic acid backbone, influencing its sensory properties and biological interactions. This compound has been identified as a significant contributor to the odor of anxiety sweat, alongside other fatty acids (PMID:40301685 ). Research indicates that it is perceived differently between sexes, with women finding it less pleasant compared to men, which may relate to its role in sexual dimorphism (PMID:38216326 ). Additionally, 3-hydroxy-3-methylhexanoic acid is involved in various olfactory pathways, as studies have examined its detection thresholds and perceptual descriptions across different cultures (PMID:31178171 ). It is also produced by specific skin bacteria, such as Staphylococcus epidermidis, which liberate it through metabolic processes (PMID:2778 ...). The compound's presence in axillary odor and its significant reduction following plasma exposure highlights its relevance in human scent and potential implications in social and biological signaling (PMID:38321059 ).
