INTRODUCTION
In addition to functioning as substrates for protein biosynthesis or as an energy source, amino acids also act as physiological messengers in the body. Amino acids may be classified based on the physical and chemical properties of their R groups such as acidic, basic, aromatic, sulfur, uncharged hydrophilic or inactive hydrophobic amino acids. In addition, L-proline has a special structure. Basic amino acids include L-lysine (L-Lys), L-arginine (L-Arg) and L-histidine (L-His), in chickens, these three amino acids are nutritionally essential and are involved in several metabolic pathways.
The major pathway for L-Lys metabolism in the liver ...
