The Phosphorus-Containing Lipides of the Carrot

The early literature dealing with plant phospholipides was reviewed in 1930 by Thierfelder and Klenk (1) and, with the exception of a few of the most recent papers (25), the work in this field was summarized in 1941 by Working and Andrews ( The difficulties in isolating and purifying plant phospholipides and in freeing them of sugars, amino acids, etc., are brought out in these reviews. Such difficulties are particularly evident in plants like the carrot (7-13) t,hat are high in water and low in lipide content.
