Cephaalinen

Cephaalinen is not a term with a widely established meaning in current scientific literature. It may be a misspelling of cephalins, a fictional or niche term used in a specific publication, or a very old synonym no longer in common use. If the intended term is cephalins, then the article below describes the conventional meaning.

Cephalins designate a group of phospholipids historically identified in brain tissue. The principal member often associated with cephalins is phosphatidylethanolamine (pe), a glycerophospholipid that, together with related species, forms a substantial portion of cellular membranes. Cephalins are amphipathic molecules, having a hydrophilic ethanolamine head group and hydrophobic fatty acid tails, which supports their role in membrane structure and dynamics.

Biological roles of cephalins include contributing to membrane curvature and fusion events, supporting the integrity of lipid bilayers, and mediating interactions with membrane-associated proteins. They participate in various signaling pathways and can influence processes such as vesicle formation and protein trafficking under certain cellular conditions. In research settings, cephalin-type lipids are studied through lipidomics and membrane biophysics to understand their distribution, metabolism, and functional relationships with other lipids and proteins.

Occurrence and measurement of cephalins are typically discussed in the context of broader lipid profiles of tissues or cells. In modern nomenclature, researchers more often refer to specific molecules by their primary name, such as phosphatidylethanolamine or related phospholipids, rather than the historical umbrella term cephalin.

Notes: If cephaalinen appears in a text, it is advisable to verify whether it is a typographical error for cephalin/cephalins or a coined term within a fictional or niche framework.
