| Abstract Detail
Lipids Nakai, Ayako [1], Imai, Hiroyuki [2]. Sphingoid base composition of monoglucosylceramides in legumes. The sphingoid base composition of monoglucosylceramides (MGCs) was examined in the leaves of soybean, Lotus japonicus and 15 other species of leguminosae. In each species, the MGCs mainly consisted of 8-unsaturated sphingoid bases, with the majority of 4-hydroxy-8-E- and 4-hydroxy-8-Z-sphingenines [ t18:1(8E) and (8Z)]. The MGCs form soybean, white clover and Lotus japonicus contained 4-E, 8-E- and 4-E, 8-Z-sphingadienines [d18:2(4E,8E) and (4E,8Z)] as major components. In contrast, pea and broad bean (Vicia faba) MGCs contained mostly 8-E- and 8-Z-sphingenines [d18:1(8E) and (8Z)], suggesting that legumes can be classified in two groups of a type with many 4,8-sphingadienines and a type with many 8-sphingenines.
