Rat liver microsomes and mitochondria contain an amidohydrolase which catalyzes the hydrolysis of N-acylethanolamine to ethanolamine and fatty acid. The enzyme is active over a wide range of pH, does not require divalent cations, and is inhibited by sulfhydryl-reactive agents. The detergents Triton X-100, sodium cholate, and sodium dodecyl sulfate are also(More)
N-Acylethanolamine phospholipids were identified in the central nervous system of the fresh water fish, pike (Esox lucius) and carp (Cyprinus carpio), at levels ranging from 0.1 to 0.9% of total phospholipid. The N-acylethanolamine phospholipids of carp brain were isolated and characterized by chemical, biochemical and spectroscopic methods. Two major(More)
Dog brain homogenates and subcellular preparations incubated in the presence of Ca2+ produced a new phospholipid that was isolated and identified by its infrared spectrum and by chemical degradation as a mixture of 1,2-diacyl, alkenylacyl, and alkylacyl sn-glycero-3-phospho(N-acyl)ethanolamines, 50, 45, and 5%, respectively. The N-acyl groups consisted(More)
The phospholipids of human platelets were isolated and analysed for their constituent 1-0-alkyl- and 1-0-(1'-alkenyl)glycerol species. The serine and inositol phospholipids contained only small amounts (0.5-1.6%) of both alkylacyl and alkenylacyl species; the ethanolamine phospholipids contained little alkylacyl (1.7%) but much more alkenylacyl (45.3%)(More)
