There is increasing evidence to support the view that during dehydration oxygen radicals play a role in mediating the degradative reactions that precede loss of membrane integrity (Price et al. 1989; Quartacci & Navari-Izzo 1992; Sgherri et al. 1993). Oxygen radicals are normally produced in biological tissues as a consequence of oxidative metabolism and electron transport. In normal conditions these reactions are tightly controlled, but during stress radicals become cytotoxic and cause an oxidative injury to cellular components.

Abstract
There is increasing evidence to support the view that during dehydration oxygen radicals play a role in mediating the degradative reactions that precede loss of membrane integrity (Price et al. 1989; Quartacci & Navari-Izzo 1992; Sgherri et al. 1993). Oxygen radicals are normally produced in biological tissues as a consequence of oxidative metabolism and electron transport. In normal conditions these reactions are tightly controlled, but during stress radicals become cytotoxic and cause an oxidative injury to cellular components.File in questo prodotto:
