"Cryoprotectant" Natural Recordings by Native Speakers
A cryoprotectant is a substance that helps to protect living cells or tissues from damage caused by the freezing process. It is often used to preserve cells, tissues, and organs for cryopreservation, which is a technique used to store biological materials at very low temperatures, typically around -180°C. Cryoprotectants work by reducing the formation of ice crystals within the cells, which can cause damage and death, by binding to water molecules and preventing them from freezing. Examples of cryoprotectants include sugars, polyols, and other solutes.
Cryopreserved refers to something that has been preserved or frozen at very low temperatures, typically using liquid nitrogen, in order to halt or slow down metabolic processes, such as biological or chemical reactions.
