Which phospholipid is key component of lung surfactant?a,phosphatidylyserine b,cardiolipin c,phosphatidylcholine d,phospatidylinositol.

Answer 1

The key component of lung surfactant is **c, phosphatidylcholine**. Specifically, the most abundant form found in lung surfactant is dipalmitoylphosphatidylcholine (DPPC), which plays a crucial role in reducing surface tension in the alveoli of the lungs, preventing collapse during exhalation.
