is there really something as EBK-EBDP ? i tried to figure out what E-BK was...

[Aeon Psyche]

Or was this a typo : s

 

[S.J.B.]

BK is just "beta-keto", so the "E" modifier doesn't make sense. I think this is a typo and what is being referred to is bk-EBDP a.k.a. ephylone.

 

[Aeon Psyche]

Thought so.
