[The role of ketone bodies in energy supply in cold-blooded animals during winter starvation].

Natural winter starvation has been studied for its effect on the content of ketone bodies, oxaloacetate, glucose, 3-oxybutyrate-dehydrogenase activity level in the carp fry tissue. A compensatory mechanism of the energy supply in peripheral tissues is found proceeding by formation of ketone bodies in the liver and their distribution in the tissues of white muscles and brain. For the latter the ketone bodies in wintering serve as an additional oxidation substrate.
