Amniotic fluid (AF) is a protective pool and a resource of amino acids for the growing fetus. In study 1, we investigated if any of these AF amino acids at mid gestation were associated with fetal development in humans. Nineteen amino acids differed across birth weight percentiles. Arginine, 3-methyl histidine and tryptophan were positive predictors of birth weight, while ornithine was a negative predictor. In study 2, we used a diet induced model of IUGR to see if specific AF amino acids were predictive of fetal weight near term. Methionine and phenylalanine were modified by diet, and 12 amino acids were independently modified by gestational age, respectively. Cysteine, lysine, methionine and tyrosine were predictors of fetal weight. Thus, the AF amino acid pool is associated in animals and humans with fetal growth.
