Trehalose, also known as mycose or tremalose, is a natural alpha-linked disaccharide formed by an α,α-1,1-glucoside bond between two α-glucose units.In 1832, H.A.L. Wiggers discovered trehalose in an ergot of rye, and in 1859 Marcellin Berthelot isolated it from trehala manna, a substance made by weevils, and named it trehalose. It can be synthesised by bacteria,fungi, plants, and invertebrate animals. It is implicated in anhydrobiosis — the ability ofplants and animals to withstand prolonged periods of desiccation.
