I would like to draw the figure shown below
As you can see, the arrows from the "NAPQI" named molecule, are not really where they belong. I would like to make further arrows from the NAPQI molecule on. Can anyone help?
my code:
\documentclass[12pt,a4paper,twocolumn]{article}
\usepackage{chemfig}
\begin{document}
\schemestart
excretion
\arrow{<-}[90] APAP-sulf
\arrow{<-[SULT][sulfation]}[0,1.3]
\chemname{\chemfig[][]{@{HO}{HO}-[:30]*6(-=-(-NH-[:-30](=[:-90]@{O}{O})-[:30])=-=)}}{Acetaminophen}
\arrow{->[UGT][glucorination]}[0,1.3]APAP-gluc
\arrow {->}[-90] excretion
\arrow{->}[-150,2,opacity=0] \chemname{\chemfig{{O}=[:30]*6(-=-(=N-[:-30](=[:-90]{O})-[:30])-=-)}}{NAPQI}
\arrow{<-[CytP450][N-hydroxylation]}[90]
\arrow{->}[-90, opacity=0]\arrow{->}APAP-S-proteine
\arrow{->}[-90, opacity=0]
\arrow{<-}APAP-SG
\schemestop
\end{document}
