The free amino acids were estimated by ion-exchange chromatography in plasma of 92 samples from 46 infants of birthweight less than 2500 g; data for 23 amino acids, taurine and ethanolamine were compared with those in term infants and adults. Tyrosine values were high in 16 infants. Some other amino acids showed large changes in the first few days but by the end of the first week patterns were stable.
