Trehalose CAS 99-20-7

Trehalose, also known as α, α-trehalose, α-D-pyranose glucopyranosyl-α-D-pyranose glucoside, Mycose, is a non-reducing disaccharide formed by dehydration condensation between the hemiacetal hydroxyl groups on the anomeric carbon atoms (C1) of two molecules of D-pyranose. It is mainly divided into three types: α, α-trehalose, α, β-trehalose and β, β-trehalose. It exists in molds, algae, dry yeast, ergot, etc., and can also be synthesized artificially. It has the special function of preserving biological vitality and can effectively protect the structure of cell membranes and proteins, so that organisms can remain moist in abnormal conditions such as high-temperature dehydration (drying, high osmotic pressure) and freezing, and prevent nutrient loss and cell damage caused by cell dehydration. Trehalose in vitro also has the characteristics of stabilizing biological membranes and protein structures. It is used internationally to protect genetically engineered enzymes, various viruses, vaccines, antibodies, protein factors, nucleic acids, etc. At the same time, it is used as a stabilizer and protector for biologically active substances. It has broad application prospects in food, health products, cosmetics, medicine, molecular biology and agriculture.
