Abstract

The fatty acid composition of the triglycerides, glycerophospholipids and glycophospholipids of soyabean was compared. The fatty acids of the glycophospholipids, which are derivatives of phytosphingosine, are composed of 80% α‐hydroxy long chain acids (chain length >18) and 20% non‐substituted fatty acids, about two third of which were long chain ones. The glycerides and the glycerophospholipids contained only about 1% each of oxidised and long chain fatty acids. Among the oxidised fatty acids of the glycerides and glycerophospholipids some hydroxy acids were found, which carried the hydroxy group not at the α‐position, but rather in the middle of the chain. All the fatty acids of the glycophospholipids were ‐ contrary to the fatty acids of the glycerides and glycerophospholipids ‐ completely saturated and include appreciable amounts of odd numbered components.
