Free amino acids and urea were analyzed in 78 human milk samples obtained during the first 5 wk of lactation from 10 mothers delivering at term. Significant differences (p &lt 0.05) in the concentrations between colostral and mature milk were found for glutamic acid, glutamine, alanine, glycine,...
