A lipid bilayer surrounding the cytoplasm of a cell; a plasma membrane, a cell membrane; esp. one immediately within the wall of a plant cell. (OED)
"The inner surface of the plasma membrane is rich in phsophatidylserine, making the erythrocyte inside-out vesicle a good model for studying the translocation of diacylglycerol kinase and protein kinase C from cytosol to the inner aspect of the plasmalemma."
- Besterman et al., "Diacylglycerol-induced translocation of diacylglycerol kinase: Use of affinity-purified enzyme in a reconstitution system", Proceedings of the National Academy of Sciences 83:9378 (1986).
These days I think we use the term "plasma membrane", but, if you are going to use plasmalemma, I do wholeheartedly endorse the use of the plural plasmalemmata. (Maybe if you're talking about intercellular interactions?)
