The caption for the picture of isoalloxazine mentions an R-group. This isn't present in the picture, on top of which the substitution to convert isoalloxazine into flavins happens at not one, but three positions round the ring system.

Someone must have changed the picture without changing the caption. I've removed reference to the R group now. -- Ed ( Edgar181) 14:42, 25 April 2012 (UTC) reply
