Abstract
The major phosphate ester in plant saps has been identified as phosphoryl choline (PC) by chromatography and electrochromatography. PC has Rf values 0.9 in phenol: 0.3 in butanol-propionic acid-water. PC 11 in 0.1M lactic acid. The organic solubility and zwitter ion nature of PC suggests its possible role as a carrier for K easily transported through cell membranes. PC14 is formed only slowly by photosynthesis in C14O2 but is labeled rapidly by choline precursors such as H2C14O, HC14 OOH and glycolate-2-C14.This publication has 6 references indexed in Scilit:
