Fishes and Glycerol

Some fishes can produce extremely high levels of glycerol in their blood. Glycerol is a gentle, non-toxic 3-carbon alcohol. So, unlike many other potential solutes and antifreeze, it can be highly abundant without damaging cells and or contents. At high concentrations, glycerol is an effective antifreeze agent and ...

Solution Summary

This solution discusses the survival of fish in arctic conditions with a particular reference to the presence of glycerol in the blood.
