Protein Synthesis Capacity

Meaning

Protein Synthesis Capacity refers to the physiological ability of cells, particularly in muscle, bone, and skin tissue, to efficiently and rapidly manufacture new proteins from amino acid substrates, a process essential for tissue repair, growth, and structural integrity. This capacity is a critical determinant of an individual’s anabolic drive, directly correlating with the maintenance of lean body mass, wound healing, and overall metabolic health. Age-related decline in this capacity is a hallmark of sarcopenia and tissue frailty.
