体臭通常表现为汗臭及其他异味,在炎热的夏季比较明显。皮肤病专家认为,医学上称为体臭的气味主要来源于汗液。汗的基本成分本来是毫无味道的水,所谓汗味实际上来源于只占汗水0.8%的一种高级脂肪酸,皮肤上繁殖的一些常见菌类就以脂肪酸为食物,然后将其分解成了散发异味的甲基丁酸等低级脂肪酸。 Body odor is usually manifested as sweat and other odor, more obvious in the hot summer. Dermatologists believe that the smell of body odor, which is medically known, comes mainly from sweat. The basic component of sweat was originally tasteless water, the so-called sweat actually derived from only a high fatty acids of sweat 0.8%, some of the common fungus breeding on the skin to fatty acids as food, and then broken down into Odor-emitting methyl butyrate and other lower fatty acids.
