Short Description:

Trehalose CAS 99-20-7


Trehalose, also known as α, α - trehalose, α - D-glucopyranosyl - α - D-glucopyranoside Mycose, A non reducing disaccharide formed by dehydration condensation between the hemiacetal hydroxyl groups on the anomeric carbon atom (C1) of two molecules of D-glucose pyranose. It is mainly divided into three types: alpha, alpha trehalose, alpha, beta trehalose, and beta, beta trehalose. It exists in fungi, algae, dry yeast, ergot, etc., and can also be artificially synthesized. It has a special function of preserving biological vitality, effectively protecting the structure of cell membranes and proteins, allowing organisms to remain moist inside cells under abnormal conditions such as high temperature dehydration (drying, high osmotic pressure) and freezing, preventing nutrient loss and cell damage caused by dehydration Moreover, in vitro trehalose also has the characteristic of stabilizing biofilm and protein structure. Internationally, it is used to protect genetic engineering enzymes, various viruses, vaccines, antibodies, protein factors, nucleic acids, etc.
