WebMay 8, 2024 · Phosphatidylcholine, also referred to as lecithin, is one of the phospholipids present in mature surfactant. It is stored and secreted by organelles called lamellar bodies. [3] These organelles appear after 22 to 24 weeks gestation. Before the 28th week of gestation, the fetal lung primarily synthesizes sphingomyelin, a nonpulmonary lipid. WebApr 12, 2016 · In amniotic fluid, T2 to T3 transition was associated with decreasing levels of glucose, carnitine, amino acids (valine, leucine, isoleucine, alanine, methionine, tyrosine, and phenylalanine) and increasing levels of creatinine, succinate, pyruvate, choline, N,N-dimethylglycine and urocanate. sharpmd-s50

WebPhosphatidylglycerol (PG) and lecithin/sphingomyelin ( L S) ratios were stimultaneously determined in 1770 samples of amniotic fluid. PG was defined as "present" when it appeared in at least 2% of the total phospholipids. Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant 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 head group substituent glycerol is bonded through a p… WebThe presence of phosphatidylglycerol in amniotic fluid has been related to fetal lung maturity and the absence of respiratory distress syndrome. Amniotic fluid samples from 235 amniocentesis procedures and vaginal pool collection at varying gestational ages were analyzed for L:S ratio, fluorescence polarization, and phosphatidylglycerol. sharp material scissors
