Fig. 1. Map of metabolic pathways involving amino acids showing significant differences in the blood plasma and follicular fluid levels between groups (Kyoto Encyclopedia of Genes and Genomes, KEGG): 1 — biosynthesis of phenylalanine, tyrosine and tryptophan; 2 — phenylalanine metabolism; 3 — biosynthesis of arginine; 4 — tryptophan metabolism; 5 — alanine, aspartate and glutamate metabolism; 6 — arginine and proline metabolism; 7 — cysteine and methionine metabolism; 8 — biosynthesis of aminoacyl-tRNA. Small Molecule Pathway Database (SMPDB): 1 — aspartate metabolism; 2 — urea cycle; 3 — arginine and proline metabolism; 4 — ammonia processing; 5 — biotin metabolism.). The Y-axis and the node color reflect statistical significance of the identified amino acids’ involvement in appropriate metabolic pathways; the x-axis and the node radius reflect the studied metabolites’ effect of the pathway
