Talk:Sphingomyelin

Untitled
The introduction states that sphingomyelins can have a PC or PE head group. Subsequent portions of the article only mention a PC head group, and most of the scientific literature assumes a PC head group. Can someone knowledgeable comment on the presence of PE on sphingomyelins? 158.111.236.80 (talk) 20:56, 6 August 2015 (UTC)
