transmembrane
This term is a specialized technical descriptor used almost exclusively in biochemistry and cell biology. It describes a specific spatial orientation where a molecule, usually a protein, physically penetrates the entire thickness of a lipid bilayer. This distinguishes it from peripheral proteins, which merely attach to the surface of the membrane.
In a scientific register, the word functions as a precise anatomical marker. It is rarely used outside of academic or medical contexts and does not have a metaphorical or casual application in standard English.
