Why energy fades with age: Missing membrane lipid may destabilize mitochondria

The Hidden Chemistry of Aging Mitochondria
As we age, mitochondria lose flexibility and energy efficiency. The membrane lipid phosphatidylcholine plays a key role in this process: when its production decreases, mitochondrial function deteriorates significantly. Credit: FLI / Kerstin Wagner; AI-generated with Google Gemini

Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges of modern biomedicine. The focus is particularly on mitochondria—tiny cellular organelles long known as the cell’s powerhouses but now understood as dynamic control centers that not only produce energy, but also coordinate cellular communication, adaptation, and many of the processes essential for life.

They supply us with the energy that our body needs for movement, growth, and re...
