13C and 1H NMR Study of Lysophosphatidylcholine (LPC) Isolated from the Surface of Wheat Starch Granules

Abstract

Lysophosphatidylcholine (LPC) has been isolated from the surface of starch granules by extraction and subsequent chromatographic purification. The purified extract was examined by mono and bidimensional ¹H and ¹³C NMR and identified as LPC. The NMR information also allowed the assignment of the length and nature of the acyl chains (18—20 carbon atoms, saturated).

Se ha aislado lisofosfatidilcolina (LPC) de la superficie de gránulos de almidón mediante extracción y posterior purificación cromatográfica. El extracto purificado se analizó por espectroscopía de RMN de ¹H y ¹³C mono y bidimensional, lo que permitió identificarlo como LPC. Las cadenas acilo se identificaron como cadenas pertenecientes a ácidos saturados de 18—20 átomos de carbono.
