A comparative analysis of two types of cryoprotectants, antifreeze gly
coproteins from Atlantic cod (Gadus morhua) and carbohydrates from hem
olymph of amphypod 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 c
rystals formed. Noncolligatyve and colligatyve mechanisms of action ar
e characteristic correspondingly for glycoproteins and carbohydrates.
