Phosphatidylglycerol
Phosphatidylglycerol is a member of the class of compounds known as glycerophosphates. Glycerophosphates are compounds containing a glycerol linked to a phosphate group. Phosphatidylglycerol is soluble (in water) and a moderately acidic compound (based on its pKa). Phosphatidylglycerol can be found in a number of food items such as green bell pepper, fig, papaya, and carrot, which makes phosphatidylglycerol a potential biomarker for the consumption of these food products. Approximately 98\\% of alveolar wall surface area is due to the presence of type I cells, with type II cells producing pulmonary surfactant covering around 2\\% of the alveolar walls. Once surfactant is secreted by the type II cells, it must be spread over the remaining type I cellular surface area. Phosphatidylglycerol is thought to be important in spreading of surfactant over the Type I cellular surface area. The major surfactant deficiency in premature infants relates to the lack of phosphatidylglycerol, even though it comprises less than 5\\% of pulmonary surfactant phospholipids. It is synthesized by head group exchange of a phosphatidylcholine enriched phospholipid using the enzyme phospholipase D .
