INDICATORS OF THE AMINO ACID PROFILE IN NEWBORNS OF DIFFERENT GESTATIONAL AGE

He values of the amino acid profile indicators: alanine, arginine, glutamine, glycine, ornithine, tyrosine, methionine, phenylalanine, citrulline in dry blood spots in newborns of different gestational age were determined. Lower levels of alanine, glutamine, glycine and elevated concentrations of arginine and tyrosine were found in premature infants compared with full-term newborns. A correlation of positive average strength was found in full-term infants between the level of citrulline and total protein (r=0.42), negative average strength in premature infants between citrulline and creatinine (r=-0.51).
