Antifreeze proteins （AFPs） are proteins that have the ability to inhibit the growth of the ice. These proteins cause a non-colligative depression of the freezing point of water below that of the melting point ,so they are also named as thermal hysteresis proteins （THPs）. Recently, studies on insect antifreeze proteins achieved great advances and about twenty kinds of insect AFPs were isolated. In this paper a review about the present study of insect antifreeze proteins was given in terms of the structures of proteins and their biological properties, as well as the...
