Examples
“Lysine is found in high amounts in chicken and eggs.”
“Because the human body cannot synthesize lysine, it is necessary to include lysine-rich foods like beans and lentils in the daily diet.”
“The deficiency of lysine in certain plant-based diets can lead to a limiting amino acid profile, where the lack of this specific nutrient restricts the body's ability to utilize other available proteins effectively.”
