Trehalose (also known as mycose or tremalose) is natural α-linked 1,1-Glucose disaccharide, which means the structure lacks a reducing end and very resistant to acidic hydrolysis. In nature, trehalose can be found in animals, plants, and microorganisms. The trehalose is then broken down into glucose by the catabolic enzyme trehalase. A number of application areas of trehalose are currently being explored, for example treatments of amyloidosis, depression and dry eyes.
FITC-Trehalose (Fluorescein isothiocyanate trehalose) is a fluorescent derivative of trehalose that has an Absmax of 493 nm and an Emmax of 520 nm. FITC-trehalose has a molecular weight of 731.7 Da.
