Membrane during freezing, mechanical

From these results it can be concluded that damage to mitochondrial membranes, as observed in this study, was more closely related to the extent of ice formation than to the size of ice crystals. Therefore, this damage might not be caused by mechanical injury of membranes but rather by removal of water from the membranes during freezing or, in other words, by a dehydration process. Water is necessary for the... [Pg.199]

Little is known concerning mechanisms by which these proteins prevent inactivation of thylakoids during freezing, but they somehow contribute to membrane stabilization. They act with some specificity, since cryoprotective proteins from spinach not only fail to protect red blood cells during freezing but are actually injurious. [Pg.184]

Membranes are intolerant of freezing, drying, and mechanical abuse therefore, they usually are impregnated with glycerol during shipping and handling. [Pg.830]
