Вот ответ, но только на русском:

Свойства белков  таковы:

а) Разная растворимость в воде. Растворимые белки образуют коллоидные растворы.

б) Гидролиз - под действием растворов минеральных кислот или ферментов происходит разрушение первичной структуры белка и образование смеси аминокислот.

в) Денатурация - частичное или полное разрушения пространственной структуры, присущей данной белковой молекуле. Денатурация происходит под действием:

                                     - высокой температуры

                                     - растворов кислот, щелочей и                концентрированных растворов солей

                                     - некоторых органических веществ (формальдегида, фенола)
