In [[enzymology]], a '''ceramide cholinephosphotransferase''' ({{EC number|2.7.8.3}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:CDP-choline + N-acylsphingosine <math>\rightleftharpoons</math> CMP + sphingomyelin

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[CDP-choline]] and [[N-acylsphingosine]], whereas its two [[product (chemistry)|products]] are [[cytidine monophosphate|CMP]] and [[sphingomyelin]].

This enzyme belongs to the family of [[transferase]]s, specifically those transferring non-standard substituted phosphate groups.  The systematic name of this enzyme class is '''CDP-choline:N-acylsphingosine cholinephosphotransferase'''. This enzyme is also called '''phosphorylcholine-ceramide transferase'''.  This enzyme participates in [[sphingolipid metabolism]].
