FAQ
Frequently Asked Questions
Cardiolipin is a specific type of phospholipid, essential for the structure and function of mitochondria, the energy-producing organelles in cells.
It is important because the immune system can produce antibodies against it. These 'anti-cardiolipin antibodies' are a key diagnostic marker for antiphospholipid syndrome, a disorder that increases the risk of blood clots and pregnancy complications.
No. Although it was first discovered in beef heart tissue, cardiolipin is found in the mitochondria of nearly all eukaryotic cells (cells with a nucleus), not just heart cells.
Almost certainly not. It is a highly specialised term used only in scientific, clinical, and academic contexts related to biochemistry, cell biology, and immunology.
