| Abstract: | Methyl enol ethers are detected within the capillary gas chromatographic profiles of aldehyde dimethyl acetals derived from human red cell plasmalogens or from a synthetic aldehyde mixture. They arise from the dimethyl acetals via methanol elimination as artefacts of the injection technique. In a nutritional experiment, the probands showed a rising proportion of dimethyl acetals in the phospholipid fraction of their erythrocyte ghosts; this fact is seen as an effect of the lipid composition of the milk fat administered. |
