Abstract/OtherAbstract:
|
In developing seeds of Perilla frutescens var. crispa, the triacylglycerol fraction was found to accumulate between 15 and 19 days after flowering. Of this, 65% of the total fatty acids was alpha-linolenic acid in the mature seeds, with the latter being esterified in comparable amounts at all positions (sn-1, 2 and 3) of the glycerol residue. It was also demonstrated that, 1-acylglycerol-3-phosphate acyltransferase, which catalyzes esterification at the sn-2 position of the glycerol backbone, showed low activities for alpha-linolenoyl-CoA as substrate. These findings suggest that the diacylglycerol precursor for triacylglycerol synthesis is not directly derived from phosphatidic acid through the glycerol phosphate pathway. |
