Trehalose, also known as mycose, is a natural alpha-linked disaccharide formed by an alpha, apha-1,1-glucoside bond between two alpha-glucose units. In 1832 Wiggers discovered trehalose in an ergot of rye and in 1859 Berthelot isolated it from trehala manna, a substance made by weevils, and named it trehalose. It can be synthesized by fungi, plants, and invertebrate animals. It is implicated in anhydrobiosis
