Sweat: Watery Secretion of Sweat Glands

Sweat is a watery secretion that is excreted through so-called sweat glands via the skin. Sweat consists of over 99% water. In addition, various salts are among its other components. Fresh sweat is almost odorless. It is only the breakdown of long-chain fatty acids into shorter chains such as butyric acid or formic acid that causes the typical sweat odor. Various bacteria, which use sweat as an optimal breeding ground, are responsible for this.
