The acid present in sweat is lactic acid. This acid is a byproduct of anaerobic metabolism, meaning it's produced when your body doesn't have enough oxygen to fuel its energy production. Lactic acid is released into the bloodstream and can eventually be excreted through sweat.
Sweat also contains other substances like water, minerals, lactate, and urea. The presence of lactic acid in sweat can influence the attraction of certain insects, such as mosquitoes, as they are attracted to the ammonia and lactic acid present in eccrine sweat.
