Cryoprotectant - Wikipedia
WebA cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants ( antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods.
