Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant [1] and in the plasma membrane where it directly activates lipid-gated ion channels. The general structure of phosphatidylglycerol consists of a L-glycerol 3-phosphate backbone ester-bonded to either saturated or unsaturated fatty acids on carbons 1 and 2.
The pregnancy category of a medication is an assessment of the risk of fetal injury due to the pharmaceutical, if it is used as directed by the mother during pregnancy. It does not include any risks conferred by pharmaceutical agents or their metabolites in breast milk .
Topical nicotinamide and topical zinc are safe, however, there are no FDA pregnancy category ratings. [27] [28] Topical salicylic acid and topical dapsone are classified as FDA pregnancy category C. [23] [28] Acne medications to avoid during pregnancy include oral isotretinoin and topical tazarotene as there have been reports of birth defects.
Pulmonary immaturity has also been proposed as a causative factor. Levels of phosphatidylglycerol (an indicator of lung maturity) were found to be negative in certain newborns. Mild deficiency of pulmonary surfactant has also been suggested as a causative factor.
AmBisome (liposomal amphotericin B; LAMB) is a liposomal formulation of amphotericin B for injection and consists of a mixture of phosphatidylcholine, cholesterol and distearoyl phosphatidylglycerol that in aqueous media spontaneously arrange into unilamellar vesicles that contain amphotericin B. [17] [26] It was developed by NeXstar ...
Phosphatidylglycerol is a precursor and structural isomer of LBPA. [1] LBPA's stereochemistry is atypical among glycerophospholipids and influences its function within the LE/LY (late endosome/lysosome) system. [1] [2] LBPA makes up 15–20% of all LE/LY phospholipids and is not found in other subcellular membranes. [3]

The lecithin–sphingomyelin ratio is a marker of fetal lung maturity. The outward flow of pulmonary secretions from the fetal lungs into the amniotic fluid maintains the level of lecithin and sphingomyelin equally until 32–33 weeks gestation, when the lecithin concentration begins to increase significantly while sphingomyelin remains nearly the same.
