14:0 Cardiolipin (sodium salt) is widely used in research to study mitochondrial function and membrane dynamics. It plays a critical role in maintaining the structural integrity of mitochondrial membranes and is essential for the proper functioning of enzymes involved in oxidative phosphorylation. Researchers utilize it to investigate cellular respiration, apoptosis, and mitochondrial-related diseases such as Barth syndrome. Additionally, it serves as a key component in model membrane systems to explore lipid-protein interactions and membrane biophysics. Its application extends to drug development, where it helps in understanding the impact of therapeutics on mitochondrial health.
