Regulation of maternal phospholipid composition and IP(3)-dependent embryonic membrane dynamics by a specific fatty acid metabolic event in C. elegans.

Natural fatty acids (FAs) exhibit vast structural diversity, but the functional importance of FA variations and the mechanism by which they contribute to a healthy lipid composition in animals remain largely unexplored. A large family of acyl-CoA synthetases (ACSs) regulates FA metabolism by esterifying FA to coenyzme A. However, little is known about how particular FA-ACS combinations affect lipid composition and specific cellular functions.
