🧪Proteins make up 55% of the cell membrane composition.
🔬Integral and peripheral proteins are the two types of proteins present in the cell membrane.
🧫Phospholipids are the major lipid component, with phosphoserine being an important phospholipid.
💉Cardiolipin is an essential phospholipid mainly present in mitochondria.
⚠️Anti-cardiolipin antibodies are seen in diseases like antiphospholipid antibody syndrome and syphilis.
