Comportamiento termotrópico de los fosfolípidos, revisión bibliográfica

Abstract

The aim of this study was to identify the state of the art of the thermotropic behaviour of phospholipids upon temperature change. The methodology was based on a systematic search of the topic in four databases of high-impact global popular science publishers: SPRINGER, PUBMED, ELSEVIER and ACS PUBLICATIONS; then it was proceeded to create our own database in Excel, in which the selected topics were placed for further study and analysis, the results of which were reflected in tables and graphs. A total of 53 scientific papers were obtained, which provided important information for understanding the thermotropic behaviour of lipids. The results of these studies indicated that phospholipids, the main components of the lipid bilayers of prokaryotic and eukaryotic cells, present phase transition changes when subjected to a certain temperature known as transition temperature, which is specific to each phospholipid; besides, the addition of other components to the bilayer such as carbohydrates or proteins affects their thermotropic behaviour because when they are located between the head and tail of the phospholipids they lead to a decrease in the Van der Walls forces, altering the transition temperature. In conclusion, this literature review study helps to identify the thermotropic behaviour of phospholipids. Experimental studies are recommended to corroborate the results.
