zeiffelz Posted May 22, 2004 Share Posted May 22, 2004 Hi, have some doubts about antifreeze proteins cos i just learnt about them, so am a beginner here. Firstly, are there any other froms of antifreeze proteins, say creating a artificial, "fake" antifreeze proteins? Then how do these antifreeze proteins actually help to retard or stop the forming of ice? Thank you! Link to comment Share on other sites More sharing options...
Skye Posted May 22, 2004 Share Posted May 22, 2004 Where did you learn about them? I've only heard of sugars being used to prevent ice crystals forming. Link to comment Share on other sites More sharing options...

Skye Posted May 22, 2004 Share Posted May 22, 2004 Here's a site about them: http://people.hofstra.edu/faculty/peter_c_daniel/Animal_Physiology/special_topics_fall2001/Temperature/arctic%20flounder/Website/ Basically they are glycoproteins (proteins with sugas molecules attached) that bind to the faces of ice crystals and prevent more water molecules from attaching and thus stop crystal growth.

Tesseract Posted May 22, 2004 Share Posted May 22, 2004 Theres been alot of threads about antifreeze lately, its not even snowing where I am. Link to comment Share on other sites More sharing options...
daisy Posted May 28, 2004 Share Posted May 28, 2004 When I'm freezing down cells I use either glycerol or DMSO (Dimethylsulphoxide) to prevent ice crystal formation....hope that helps. Link to comment Share on other sites More sharing options...
