However, there is little direct information about its site of synthesis or pathway of synthesis. Alveolar macrophages (>90 percent pure by light microscopy and < 0.5 percent with lamellar bodies by electron microscopy), peritoneal exudates (> 90 percent heterophils), and slices of the lung and liver from. Dipalmitoylphosphatidylcholine (DPPC) is a phospholipid (and a lecithin) consisting of two C 16 palmitic acid groups attached to a phosphatidylcholine head-group.. It is the main constituent of pulmonary surfactants, which reduces the work of breathing and prevents alveolar collapse during breathing

Dipalmitoyl phosphatidylcholine (a.k.a. lecithin) is a major component of pulmonary surfactant and is often used in the L/S ratio to calculate fetal lung maturity. While phosphatidylcholines are found in all plant and animal cells, they are absent in the membranes of most bacteria, including Escherichia coli All of the data are consistent with the view that alveolar macrophages synthesize dipalmitoyl lecithin via the cytidine diphosphate-choline pathway.

the period 1964-7 was synthetic dipalmitoyl-lecithin (DPL) prepared as an aerosol either in a mixture ofpropylene glycol andwater orin afreon carrier.2 3 Theresults were uniformly disappointing and treatment with surfactant was soon stopped in favour of nonspecific supportive measures. The efforts exerted by neonatologists for achievin The story of surfactant probably began in 1929 when Kurt von Neergaard, a German-born Physiologist working in Switzerland filled a porcine lung with an isotonic gum solution 'to eliminate surface tension of the air tissue interfaces'. 1 After expanding the lung with air and liquid, he concluded that 'a lower surface tension would be useful for the respiratory mechanism' and that. Abstract. There are many functional and pathologic similarities between the adult respiratory distress syndrome (ARDS) and the respiratory distress syndrome (RDS) of premature newborn infants, including a lack of surfactant in the alveolar spaces and airways [1, 2]. In ARDS, however, surfactant deficiency is a complication of lung injury rather.

  1. Dipalmitoyl lecithin act as a surfactant in the lungs. It is found in the extracellular lipid layer, lining the pulmonary alveoli, allowing it to ventilate. It develops in the lungs after the 30th week of gestation. Premature infants do not have an adequate amount of this surfactant, which may cause death due to respiratory distress syndrome

The lung is an important metabolic organ. Glucose provides the major source of substrate. Oxidative pathways are active and are required to maintain normal tissue energy stores. Synthetic activity in the lung is extensive and related mainly to synthesis of dipalmitoyl lecithin and other components of the lung surfactant system The development of the lung lesions was correlated with phospholipid (lecithin) levels in consolidated and unconsolidated infected and normal lungs. As the lungs became more and more consolidated, there was a corresponding and significant decrease in the amount of phospholipid (dipalmitoyl lecithin) compared to the amount of normal or. 1,2-Dipalmitoyl- sn -glycero-3-phosphate monosodium salt.

Le surfactant pulmonaire est un matériau complexe tensioactif sécrété continuellement dans la lumière alvéolaire par les pneumocytes de type 2.Il est constitué d'un grand nombre de molécules différentes : lipides, phospholipides et protéines. Le surfactant pulmonaire est indispensable à une fonction respiratoire normale For example, pulmonary surfactant is a mixture of lipids (primarily dipalmitoyl phosphatidyl choline [DPPC]) and proteins that controls the surface tension of the fluid lining of the inner lung (the site of gas exchange), allowing rapid expansion and compression of this lining during the breathing cycle. Phospholipids are the major lipid. La phosphatidylcholine, plus connue sous le nom de « lécithine », est un lipide de la classe des phosphoglycérides.La définition exacte de la lécithine peut dépendre du contexte. Au sens le plus strict, la lécithine désigne uniquement les phosphatidylcholines [1], [2], c'est-à-dire des lipides dont la molécule est composée d'un résidu de choline, d'un phosphate, d'un résidu de.
