Your armpits do not smell roses? For lack of a protein – Medicine

Discovery of the University of York one of the key points in the process by which odorless molecules, produced under our armpits with sweat, are transformed into volatile chemicals with a distinctly more acidic and pungent aroma, often unpleasant to smell. This paves the way for a new generation of more effective deodorants, as University of York researchers explain in the study published in the journal ELife.
The same group of researchers had already discovered that it's a small number of bacteria of the Staphylococcus species that causes the unpleasant smell that sometimes comes out of our armpits, but it's unclear how these bacteria could turn odorless molecules into nauseating. A process now less obscure because the first step has been deciphered: the molecular structure of a protein "transporter" has been identified and badyzed in detail, which allows bacteria to recognize and swallow the odorless compounds of the sweat. "The skin of our underarms provides a unique niche for these bacteria," says study coordinator, Gavin Thomas. "Today, many deodorants act a little like a nuclear bomb under the armpits, inhibiting or killing most of the bacteria present to prevent unpleasant smells, but in reality it's only a small one." many of them provoking them, "he continues. These Staphylococcus bacteria use the transport protein to recognize and swallow odorless sweat compounds that turn into bad smells. Having seen the structure of this protein will help develop new types of deodorants that can block their functioning.
