The levels of oxidized and reduced di- and triphosphopyridine nucleotide were measured in liver tissue from rats that had been exposed to cold (4° ± 1° C) for one month. These animals exhibited about 65% more TPNH and total triphosphopyridine nucleotide than control animals maintained at an ambient temperature of 25° ± 1° C. The significance of these alterations to the efficiency of oxidative phosphorylation is discussed.
