What substance forms the main component that gives vernix caseosa its waterproofing property in utero?
Answer
Lipids (oils)
The complex structure of vernix caseosa is lipid-rich, meaning it contains a high concentration of fats or oils. These lipids are crucial because they function to create a waterproof barrier around the delicate skin of the fetus while it is submerged in the amniotic fluid throughout the third trimester. This lipid barrier ensures that the skin remains soft and supple, preventing excessive water absorption, which would otherwise lead to significant skin integrity issues upon delivery.
