Respiratory Distress Syndrome (L-01)

A premature baby, shortly after birth, presents with rapid breathing, intercostal retractions, and grunting sounds while breathing. A blood gas analysis reveals low oxygen and acidosis. A diagnosis of Respiratory Distress Syndrome is quickly made. This syndrome is seen in newborns with immature lungs whose pneumocytes do not synthesize enough:

a) phosphatidyl choline

b) phosphatidyl inositol

c) sphingosin

d) sphingomyelin

e) palmitoyl CoA

 f) palmitate
