Descripción

Descripción general

This L-α-phosphatidylcholine is extracted and purified from soybeans. It serves as a substrate for specific phospholipase present in all Listeria monocytogenes and some strains of Listeria ivanovii. If L-α-phosphatidylcholine is used in a solid medium the presence of organisms possessing the specific phospholipase can be detected. The phosphatidylcholine is cleaved which results in a precipitate which can be seen as opaque halo around the colonies.

Aplicación

L-α-Phosphatidylcholine is one of several phospholipids used in membrane research and is often used as a component in liposomal drug delivery systems.
In this case it is added to culture media to differentiate the specific phospholipase producing microorganisms from those that cannot.

Acciones bioquímicas o fisiológicas

Un fosfolípido estructural principal del cerebro, que constituye aproximadamente el 15% de los lípidos totales; localizado principalmente en la materia gris.
