Relative fold change of amino acid content in the chicken egg yolk during the embryonic development. Each section presents the different amino acid subfamily that is defined by the structure or function, such as α-ketoglutarate subfamily (A), oxaloacetate subfamily (B), glycerol-3-phosphate subfamily (C), branch-chained amino acid subfamily (D), aromatic amino acid subfamily (E), and histidine subfamily (F). The fold change (y axis) was calculated by dividing the abundance of each amino acid at E07, and the abundance of each amino acids in egg yolk is displayed in Table 2.
