Abstract
1. [14C]Benzoic acid administered to rats fed a normal diet was excreted mainly (99% of 24h excretion) as hippuric acid.
2. In protein-energy malnourished rats, only about 74% of [14C]benzoic acid administered was excreted as hippuric acid. The remainder was excreted as the glucuronide conjugate.
3. The oxidative phosphorylation capacity of liver mitochondria of malnourished rats was 30% less than that of normal rat liver mitochondria.
4. The decreased rate in oxidative phosphorylation is discussed in relationship to the observed decrease in glycine conjugation.
