[Crystallization of aqueous solutions of cryoprotectors from Atlantic cod and lake Gammarus].
A comparative analysis of two types of cryoprotectants, antifreeze glycoproteins from Atlantic cod (Gadus morhua) and carbohydrates from hemolymph of amphypoid crustacean (Gammarus lacustris) has been performed. Both glycoprotein and carbohydrate antifreezes effectively decreased the freezing point of water solutions and diminished the size of ice crystals formed. Noncolligative and colligative mechanisms of action are characteristic correspondingly for glycoproteins and carbohydrates.
