Generally speaking, trehalose is d-trehalose, which is a disaccharide widely existed in nature plants, animals and microorganisms. It is formed by 2 glucose through alpha, alpha -1→1 bond. D-trehalose disaccharide refers to the d-trehalose containing two crystalline water. Trehalose is a non-reducing sugar composed of special disaccharide molecules with very stable characteristics. It can form a special protective film on the cell surface under such harsh conditions as high temperature, high cold and dry water loss, effectively protecting the biomolecular structure from being destroyed, thus maintaining the life process and biological characteristics of living organisms.
