The researchers tested the protein against various sweat components and found that one compound, 4-methylphenol, actheated the nerve cells.
Some are particularly sensitive (or insensitive) to androstenone, a component of sweat.
The technique is so named because it involves the successive deposition of two metals on the macromolecule components of sweat residue and, in consequence, develops fingerprints on an array of crime scene evidence (Saunders, 1989b).
In experiments conducted with fruit flies and the mosquito that transmits malaria, Leslie B. Vosshall and co-workers at Rockefeller University, New York City, found that DEET blocked the electrophysiological responses of the insects' olfactory sensory neurons to attractive odour compounds, including lactic acid, a component of human sweat.
The salt component of your sweat won't change much, even if you considerably cut down on your salt intake.
Horses are unusual in producing protein-rich sweat for thermoregulation, a major component of which is latherin, a highly surface-active, non-glycosylated protein.
Examples of these attractive chemicals include carbon dioxide (CO2), the ultimate catabolite of vertebrate respiratory processes, L-lactic acid, which is produced through anaerobic glycolysis in human eccrine glands, and ammonia, also a component of human sweat [5], [6], [7].
Acetate and formate derive respectively from the β- and α-oxidation of long-chain fatty acids by fibroblasts [ 32], and lactic acid is the principal organic component of eccrine sweat (and is found at higher concentrations on the palms [ 33]).
With the exception of ionic species, most of the components present in sweat are neutrally charged and have a negligible effect on conductivity.
Furthermore, a synergistic effect of ammonia, lactic and carboxylic acids, all components of human sweat, more actively secreted during fever episodes, has been described in the host-seeking behavior of A. gambiae [35].
