different types of glands, eccrine and apocrine. We have about 3 million eccrine glands, which are found in our skin and secrete sweat to cool our bodies. This sweat is mostly made up of water and salt. Apocrine glands work a little differently. There are about 2,000 of these glands, primarily found in our hair follicles. When we're stressed (physically or emotionally) they produce a sweat rich with proteins and fatty acids, including a carbohydrate called sialomucin. Sialomucin is a glycoprotein, a protein that has a sugar coating.
