Egg White Protein Promotes Developmental Growth in Rodent Muscle Independently of Leucine Content

Leucine has unique anabolic properties, serving as a nutrient signal that stimulates muscle protein synthesis.We tested whether the leucine concentration is the only factor determining protein quality for muscle development.We selected 3 dietary proteins: casein (CAS), egg white protein (EWP), and albumin (ALB), representing the leucine concentrations of ∼8.3%, 7.7%, and 6.7% of the total protein (wt:wt), respectively. In the chronic feeding...
