In addition to losing all of the genes in pathways for the human-essential amino acids, they have lost genes required for serine and arginine biosynthesis. ... All animals lack the biosynthetic pathways for isoleucine, leucine, valine, phenylalanine, tryptophan, lysine, methionine, threonine, and histidine (Table 3).
The essential amino acids (EAAs) (e.g., methionine, lysine, leucine, isoleucine, tryptophan, valine, threonine, phenylalanine, and histidine) cannot be synthesized endogenously, so 10–20 mg/kg body weight of each must be obtained in the diet each day from consumed protein.
