Abstract
Summary
A series of 48 determinations of free alpha-amino acid nitrogen was done on the urine of 39 infants, premature infants, and pre-adolescent children. The children excreted approximately 1 mg per lb per day; the infants and prematures approximately 3.9 mg per lb per day. This difference is statistically significant. The values for children were lower than those reported for adults, and no sex difference was found.
