3.6. Biochemical Analyses
At baseline, serum BUN was higher in SF and α-lac-EW than in BF infants (Serum concentrations of amino acids are presented in Mean total branched chain amino acids (BCAA—sum of isoleucine (Ile), leucine (Leu) and valine (Val)) was higher at four and six months in FF than in BF infants, but lower in α-lac-EW and CGMP-RW than in SF infants (Serum insulin and C-peptide were similar among the FF groups, and higher than in BF infants at baseline (except in α-lac-EW where insulin was similar to BF) and during the intervention period (Serum leptin at baseline, four and six months, was similar in all groups and no difference was found between boys and girls (Hemoglobin (Hb) was similar in all groups at four and six months (
