Studies in Amino Acid Utilization

Abstract

Weight-recovery of comparable pairs of protein-depleted rats was determined while the animals were fed “amino acid rations” for a 10-day period. In most instances 1 rat was offered a ration containing a mixture of 16 amino acids patterned after the amino acid composition of casein while the second received the same mixture with one indispensable amino acid omitted. In most cases the rations were reversed for a second 10-day period. In some experiments fewer amino acids were employed. The results may be listed as follows:
