| cephalin | A term formerly applied to a group of phosphatidic esters resembling lecithin but containing either 2-ethanolamine or l-serine in the place of choline; these are now known as phosphatidylethanolamine and phosphatidylserine. They are widely distributed in the body, especially in the brain and spinal cord, and are used as local haemostatics and as reagents in liver function test. Synonym: kephalin. (05 Mar 2000) |
| cephaline | Denoting members of the protozoan suborder Cephalina (order Eugregarinida), characterised by bodies divided into chambers (anterior protomerite and posterior deutomerite, or anterior epimerite, protomerite, and terminal deutomerite); all are parasites of invertebrates. (05 Mar 2000) |
