I'm using chemfig to write a reaction of sucrose degradation, but the first arrow is too near the +
sign. I tried using \indent
but it didn't work.
\definesubmol{x}{(-[4]H)(-[0]OH)}
\definesubmol{y}{(-[0]H)(-[4]HO)}
\schemestart
\chemname{\chemfig{[2]CH_2 \cdot OH-!x-!x-!y-(-[0]OH)=(-[3]H)-[1]OH}}{1, 2 Enediol}
\arrow
\indent \indent \indent \+
\arrow(--tri){0}[90,0.15]
\indent \indent \indent \chemname{\chemfig{[2]CH_2 \cdot OH-(-[0]OH)=(-[3]H)-[1]OH}}{Triosa Enediol}
\arrow(--gli){0}[-90,0.30]

\arrow(--met)
\chemname{\chemfig{[2]CH_3-(=[0]O)-(-[3]H)=[1]O}}{Metilglioxal}

\arrow(@tri--){<=>}

\schemestop
\hspace{5mm}
or something like this?
