The present study is concerned with the effects of various amino acid malnutrition situations on the level of ATP in rat liver. Since an amino acid malnutrition such as excess ethionine causes a decrease in the level of ATP, maybe other amino acid malnutrition situations will also lower the level of ATP. To test this hypothesis, the following cases were studied using weaning rats:

  1. Casein and casein with added methionine,

  2. Heated soybean meal and ray soybean meal,

  3. Casein and casein with added ethionine,

  4. Casein and casein with added leucine,

  5. Acid hydrolyzed casein with two levels of tryptophan addition, and

  6. Heated soybean meal with added valine and threonine and raw soybean meal with added valine and threonine.

The final case studied was to see if threonine and valine supplementation of raw soybean meal gave ATP levels equal to heated soybean meal.
