sphingomyelin
This term refers to a specific phospholipid that is critical for the structural integrity of the myelin sheath, which insulates axons to ensure rapid electrical impulse conduction in the nervous system. It is used almost exclusively in biochemical, medical, and neurological contexts, carrying a neutral, technical connotation.
As a chemical compound and a specific biological molecule, it is treated as an uncountable noun. It does not have a plural form in standard scientific usage; instead, quantities are described using mass units or by referring to the "levels" or "concentrations" of the substance.
Meanings
A type of sphingolipid found in animal cell membranes, particularly abundant in the myelin sheath of nerve cell axons.
The degradation of sphingomyelin by the enzyme sphingomyelinase is a key step in signal transduction.
