Alkenyl and alkyl ether phospholipids in pig mesenteric lymph node lymphocytes.

Significant amounts of alkenyl and alkyl ether phosphoglycerides were found in pig mesenteric lymph node lymphocytes. The choline phosphoglycerides are composed of 2.6% alkenyl ether and 25.7% alkyl ether compounds besides 71.7% diacyl analogs. The ethanolamine phosphoglycerides consist of 50.2% alkenyl ether, 7.8% alkyl ether and 42.0% diacyl compounds. The fatty acids chain compositions at the 1- and 2-positions of each lipid class were analyzed.
