Cardiolipins in heart --- Cardiolipin (CL) is a vital phospholipid in maintaining the structure and function of heart mitochondria. The production of CL involves both its creation and modification through the enzyme cardiolipin synthase (CLS). In a mouse model, where hearts experienced damage induced by catecholamines, researchers observed a decline in both CLS and cardiac CL species. This mirrored the complexities of love—sometimes tested by challenges. The consequences included heightened oxyg
