水中溶解度:68.9 g/100g (20°C)，溶于热乙醇，不溶于醚 Trehalose, Dihydrate, is an osmolyte, a chemical chaperone and inducer of autophagy, that has been reported to protect cells against numerous environmental stresses. This compound contains many properties that allow it to stabilize partially unfolded protein molecules and inhibit protein aggregation. These properties include a low chemical reactivity, high glass transition temperature, existence of numerous polymorphs, nonreducing nature, and high affinity for water molecules. Additionally, Trehalose has been noted to bind to expanded polyglutamines and stabilize partially unfolded polyglutamine-containing proteins. An osmolyte, chemical chaperone, and inducer of autophagy.
