The aminoethylphosphonate-containing lipids of rumen protozoa

R M C Dawson 1, P Kemp 1
PMCID: PMC1198385  PMID: 4967076

Abstract

1. A method is presented for identifying and estimating the aminoethylphosphonate (ciliatine)-containing phospholipids in a complex mixture. 2. Evidence was obtained that the phospholipids of a pure culture of Entodinium caudatum and a mixed rumen protozoa sample contain diglyceride ciliatine, and a plasmalogen ciliatine was detected in the latter. 3. A ninhydrin-positive sphingolipid was isolated from rumen protozoa. Although chromatographically homogeneous on silica gel it contains two components, which were provisionally identified as ceramide ciliatine and ceramide phosphorylethanolamine. 4. A detailed phospholipid analysis of E. caudatum and rumen protozoa is presented. They contain no phosphatidylserine or cardiolipin, but an unidentified phosphoglyceride containing a zwitterionic amino acid is present.
