Trehalose (α -trehalose, α -d-glucopyranoside, α -D-glucopyranoside, Mycose) is a non-reductive disaccharide derived from the dehydrating condensation of the hemiacetal hydroxyl group on the heterohead carbon atom (C1) of two d-glucopyranoside molecules. It is mainly divided into α, α -trehalose, α, β -trehalose and β, β -trehalose.
It is found in molds, algae, dry yeast, ergot, etc., and can also be synthesized artificially.
It has the special function of preserving biological vitality, can effectively protect the cell membrane and protein structure, so that the organism in abnormal circumstances, such as high temperature dehydration (dry, high osmotic pressure), frozen still keep the cell moist, prevent the loss of nutrients and cell damage caused by the loss of water cells.
In vitro and trehalose also has the characteristics of biological membrane and protein structure, stable international protection of genetically engineered enzymes with it, all kinds of viruses, vaccines, antibodies, nucleic acid, protein factor and so on, at the same time as stabilizers of bioactive substances and protective agent, in food, health care products, cosmetics, medicine, molecular biology and agriculture and other fields has a broad application prospect.
