Lysine is an indispensable dietary amino acid for all vertebrates and is required for protein synthesis.
The arginine requirement is influenced by many factors that vary between species. There is an antagonism that can occur between lysine and arginine in some species where excessive intakes of one of these amino acids will adversely affect the metabolism of the other amino acid thereby increasing its requirement.
Lysine is a dietary indispensable amino acid.
Lysine is the first limiting amino acid in most grain and cereal-based diets so it also defines the protein required to meet the amino acid requirements..
